i've had lucid dreams before when i didn't know what they were. i know i'm dreaming while i'm in it and several times i've controlled it slightly. however, nothing is vivid, my senses don't really work.

one really scary dream i had was when i knew i was dreaming and something undesirable happened, so i tried to wake up. usually when i close my eyes really tight or open them really wide i wake up, but in this dream i couldn't. i tried opening my eyes for probably 10-15 minutes or so and i couldn't so i started panicking like i would never wake up.

i did eventually but it freaked me out.
