I keep having dreams about the end of the world. I dont know but i have dreamt of it about 9 times this month. It repeats it self just with a different out come. In my dream i stand and stare at the ocean. Comet hits it. Ocean turns to blood. People burn and waves wake me up. Its seriously isnt cool
but remember: Dreams almost NEVER have meaning. dreams are the absolute extent of your imagination, and are caused when your subconscious connects random memories during REM sleep. If you where feeling strongly emotional towards a memory while you fell asleep, related memories are likely to appear in your dreams of that nite. remember; your brain stores EVERY single feeling, sensation, emotion, sight, and all feedback from ur senses in ur longterm memory, accesssable by ur subconscious, but only certain meomories are accessable bay your frontal lobe.
Maybe a movie, book, picture, daydream, or anything really triggered your dream sequence, and the more you worry about it, the more you'll dream of it. relax, its nothing.
