I struggle with Lucid Dreaming and it can get pretty funky during stressful times of my life. I have about 5 prominent nightmares/terrors that repeat themselves so I have been able to experience the "scripted" events and then re-experience them with me going "off-script" over the years.

One is me and 2 friends move into a new apartment, we all go into a specific bedroom and start arguing about who gets the room, suddenly one of us kicks the bed in frustration and all the lights go out while thunder and lightning strikes. When the lightning stops I look around to only see one of my friends standing beside me, the one who kicked the bed is missing. We go back out to the main area and see a shadow cast through our window of a man eating our friends guts while he screams.
