I don't even remember what i dreamt of after waking up haha. It's kinda amazing that you could still remember and piece all this information together. Even if try i only get it as fragments and they just fade away within a few minutes once I lose interest.
There are dreams some times that I forget quickly or don't even think about at all when I wake up and they disappear from memory, but some times I guess they're interesting enough and "last" until I wake up or get interrupted from waking up that stay.
I remember one time I resumed a dream after returning to sleep. It was so weird xd. That rarely happens now though. I noticed that the more I'm thinking about something, chances are they'll pop up in my dream. Nightmares are even worse because i only wake up when something bad happens haha.
