I can't remember what I was dreaming about, but I often wake up laughing. Some times it's so bad that I'm exhausted the next day. I havent done any drugs in over eight years and I rarely drink. Any ideas?
If you ever do remember your dream, be sure to post it. Another thought: could be it neurological? Sleeping induces different brain patterns. Laughing is associated with a very specific nucleus in the limbic system (I think the thalamus or hypothalamus). Are they related?
