I have the same issue. I used to get "abducted" or harassed by aliens at night. I thought it was real, lol. I am on antipsychotics now, abilify, and it happens a lot less. Even so, I still sleep with the lights on and my family gets pissed. Last time I slept with the lights off, a witch appeared and told me she was going to kill me if I didn't do a mission for her. So yeah, lights stay on for me, I don't care if it affects sleep quality
