It usually takes me a while to figure out I'm in a dream, sometimes I can control the dream but others any attempt to control what I/others do causes me to wake up. Ive even been able to move my body body while dreaming, feeling my body move under the blankets but not wake up. It was a strange sensation.
Ironically, I have an unfathomably advanced imagination; yet my sessions of REM sleep yield nothing but a time skip. Ever had one of those?
Those moments where you drift off to sleep, only to wake up in seemingly two seconds and it's eight hours. Yeah, those.
I've done that, I felt like I was just blinking, but 4 hours passed between one blink :D
