You can learn controlling the dream from within the dream.
It is called
"Lucid Dreaming".
I have some limited success in it.
Basically you have to wake up your mind in a dream WITHOUT actually waking up, then you can do anything you want in this "virtual" reality.
OF COURSE IT IS NOT AN EASY THING TO DO
Yea, this concept is really interesting. How would you define reality anyway... what is reality? Lucid dreaming might not be "real", but if you can do whatever you want in your dreams, it's pretty much a second reality
I'm pretty sure we have all had those dreams where we were absolutely 100% sure that it was real. And then when it was over, we were pretty crushed by the fact that it was just a dream. Scary shit :O
As for Gareth, dude, this sounds like everyone has been saying so far which is stress and anxiety. Trust me, I've had my share of that shit after high school before going to university. I was 19 when it started and I was experiencing the hardest time of my life and it lasted for 2 fucking years. God, how I hate those years and I never want to feel anything remotely close to that shit ever again. But when it's all over now, I'm almost glad I lived through all that, because not do I only feel stronger now, I also know how to deal with it if it happens again, and I know that it's temporary and it'll pass. So what am I talking about? Well...
First Phase: Deep depression - 2 weeks.
I couldn't eat anything and I woke up randomly, shivering like a maniac and had to force myself to eat a slice of bread or something. That phase passed, and the depression lifted off me enough so that I could atleast eat regularly.
Second Phase: Insomnia/anxiety/panic - 2~ months.
I went to bed at about 11 PM - 01 AM but remained awake until the sunrise about 5 AM, then slept for maybe 3 hours before waking up again. This lasted a couple of months so I was basically running on 3-4 hours of sleep per night for 2 months or something. This phase also had a sub-phase where I felt extreme heat coming from my abdomen, up my torso and finally to my head and it kept coming in waves. It came a little now and then everyday but the most disturbing part was that it ALWAYS came at night when I was trying to relax and sleep. This also lasted a couple months or so but started a week after the insomnia.
Parallell to the insomnia, I had severe anxiety as well. The first week of it, I was peeing every hour with a "full load", just like when you're really nervous and you want to pee... my body went into that state and stayed there for a while. Then it progressed to nausia mostly, so I was feeling nautious for probably 6 months. Imagine having a moderate hangover... every day for 6 months, that's what it felt like.
I also had panic "feelings". I'm still not sure if I had panic attacks because I ALWAYS managed to turn the tide before I got to the point where you're hyperventilating. I believe a full blown panic attack is when you have gone past that point where you are hyperventilating, and when yours limbs go numb from the hyperventilation. That never happened to me as said, but I have felt the reality fading away just like everyone else has during a panic attack, and I have gotten a rushing heart. And I always felt weak in my entire body after one of those attacks. I remember one of them vividly... I was in class at uni, I was surrounded by people and it wasn't easy to get out. I was sitting down on my chair and suddenly I felt my face go numb, my heart started rushing, my head was spinning, reality didn't seem real, breathing got harder but I forced myself not to hyperventilate... not because I knew you aren't supposed to, but because I didn't want other to notice something was wrong with me so I shut the fuck up and took it like a man (hah), and then my heart started to calm down again. This thing continued over the next phase too, but everytime it happened, the frequency from attack to attack decreased so I knew it was getting better each time I had one of 'em.
Third Phase: Extreme thinking/delusions - 4~ months.
The insomnia had passed somewhat so that I could almost get 8 hours of sleep per night, but I was constantly thinking instead. I started thinking about my existence in the universe, about God, about religion, and so on. Note that prior to all this, I was like semi-religious because I grew up that way and I "sort of" believed in God so I would pray a little every now and then silently in my head before going to sleep, but when I was praying for all of this to end... and it didn't, I stopped it all and lost all faith. Anyway, all this constant thinking made me lose track of reality and I started feeling phased out. People were talking to me and I felt like I was watching a slide show or something and I often had massive black outs and just didn't know what to say in the middle of a discussion. At one moment, I would talk about something, and in the next I would just stop because I had no clue what I was going to say. Really weird shit.
Fourth Phase: Unsocial/self doubting - 6~ months.
So in this phase, I was afraid to make or answer calls. I didn't like to be around people I didn't know. I hated going to markets to buy stuff, I hated shopping clothes. I felt like everyone was watching me all the time and I felt like everything I did was the wrong way. I felt really really outside and stupid all the time. I just didn't feel like I was worth anything, I could've just died somewhere and no one would give a fuck (haha, the truth is that nobody still would but atleast I don't FEEL that anymore
).
Fifth Phase: Recovery - Still working on it.
So after all the self doubting and shit, I began thinking "Fuck it man, I'm not dead yet and I will make it out of this crap" and that's when things really started to change. Slowly, but still... each day got better than the previous. I realized I held the key to turn this around and that it's ALL in your head. I regained some of my social skills, didn't feel as worthless all the time in public, started socializing more, and so on. As for phone calls, I still hate 'em due to the nature of talking to someone through a plastic piece of crap, but I'm not anxious anymore.
So Gareth, I've gone through a long process of shit but I know you have had lots of shit to deal with in a loooong time too... I remember you telling me about it. The total amount of medication I used during this fucked up period of my life is none, except the 4-5 sleeping pills I took during the worst nights in my insomnia phase. I never went for anti-depressive pills because I wanted to make it out by myself and I'm so glad I did it now that it's all over but I regret that I didn't take them during the early phase of this shit. It probably would have dampened the effect of many unpleasant things.
Not sure Gojira meant it in this context but nonetheless: "You have the power to heal yourself" - Esoteric Surgery, Gojira. That line has kept me going for so long =)
The most important thing is to KNOW that none of these things I mentioned are dangerous. The feeling of dying while experiencing a panic attack is not dangerous at all, so you should not fear it. Fear by itself can cause extra attacks, so do not fear it because it is not dangerous. The second important thing to know is that it's all temporary... it WILL get better, period.
Good luck with the doctor man, be open to what they say and it will go much faster! Don't feel stupid for going to "those damn doctors" like some do
Also, medication is NOT wrong. If they say there is a good chance for success with 'em, go for it. It doesn't make you any less man.
