I doubt there's anything meaningful to dreams, other than stuff you've been thinking about.
I get a lot of these archetypical sort of dreams, that many people do.
I frequently have the kind where I want to run, but cannot, these range from terrifying, to annoying. Usually, they're preceded by me running from something. I have dreams in which my teeth are falling out, which is annoying. I haven't had any cannabalism ones yet though.
I have dreams in which I can fly, which is cool, especially when they're lucid. One of the more fun ones I've had went as follows.: I dreamed that I could fly, so I was flying around. After a while, I found, to my great surprise that I was a republic-fairchild A-10, complete with missiles and 30mm rotary cannon. Now, as people cannot normally be aircraft, I deduced that I was dreaming. As such, I had fun swooping around and blowing the everloving hell out of the dreamscape below.
Oddly, the execution of flying in my dreams varies quite a bit. Sometimes it's just plain flying, others, it's kind of a floaty jumping action, and others, it's controlled by concentration. Yet other times, the flying is controlled by my breathing, like bouyancy control during scuba diving.
Sometimes I have dreams which I could swear were recurring, but I suspect instead just contain deja-vu and make me think I've had them before.
One fun dream consisted of me sitting in a lavish dining room with a made-up character of mine. We talked about aspects of it's musculostructure and manufacturer, when I came to realize that it could only tell me things I already knew. Then I got to chow down on all kinds of dream food I liked with it. Tastes just as good as real food, but it's zero calorie.
I think the most disturbing dream I've had was this: I was in some kind of space station thing. the walls were white metal and plastic, and it all seemed overexposed a bit. the floor seemed a bit curved. I was not me, exactly, in the dream. I was instead, this kind of freakish wolf-biped thing, like a crude imitation of a human made out of dog. I was only like four and a half feet tall, and my hands (paws?) had been chopped off and replaced with robot hands. my shoulders had very limited travel, because they weren't laid out like a person's.
I had a helmet over my head, and was seeing things variously through the cameras on it, and cameras outside of me, on the walls and cieling. I wandered around from the empty room I started the dream in, and quickly found friends and family members, dressed in jumpsuits, and socializing. They were just as I remember them. I started talking to them, and they recognized me as myself, and talked to me normally and friendly, except the content of what they were telling me essentially boiled down to things that would kill me. so I just talked to everyone, and they were all suggesting I do things that would make me die, and then the dream ended.
Wierd, because I've never had a suicidal thought in my life, and am a generally happy person. And I ain't no furry 'niether.
I occasionally have dreams in which I die. Funny thing is, when it happens, It's always like in the PC game Half-life. The world goes to red, and then fades to black, I hear the kind of sound that I associate with tinnitus, a kind of high pitched squeal, and it feels like my eardrums are blown in (this last bit actually does not happen when you die in halflife. Unless you have the volume up absurdly high, I guess.)
I'm interested in hearing what it's like for other people when they die in their dreams. If only to see if my experience is or is not related to playing too much videogames.
Of course, the problem with those is that I wouldn't be able to remember much of what was going on in my life at the time I had those various dreams, so they'd be useless for this project. Though I do think they give some insight into what goes on inside my head
