When I do have dreams, very rarely, they are very intense. My last dream I woke up furious for about 30 minutes before I could finally relax and calm down. When I woke up I knew I was awake and it was a dream but the anger was still there and strong for a while. I've had dreams where I've felt every emotion from happy to angry to hurt to worried to fear pretty much the whole emotional spectrum and it seems those emotions can be stronger than the ones in my waking life sometimes but I never know while I'm dreaming that it's a dream.

I've also had a dream, it was about 2 years ago that I was drowning. I stopped breathing in the dream and my body stopped breathing. After holding my breath as long as I could I started choking. The choking and coughing woke me up. It was pretty intense. I wouldn't have known if someone wasn't next to me (doing nothing about it but watching me... Yeah I left him) to tell me when I woke up about the not breathing. But the choking woke me. When you sleep you're not comatose (well not me, that's why I don't take sleeping meds) so I think things like choking and holding your breath will only last so long until you wake up... At least I hope lol

But these dreams are far and few between. It's interesting what you posted here thank you for this thread
