So, I've recently started school and have two roommates. They both said I screamed in the middle of the night at about 2am but I don't remember a thing. It was loud enough to wake them up, but I slept through it. This was three nights ago. Then the day after that one, I took a nap in the middle of the afternoon and do remember screaming just as I was about to fall asleep. Then last night, my entire bed started vibrating and I forced myself awake. It wasn't an earthquake or loud music that was causing the shaking. Am I getting closer to having my first lucid?
