I don’t get dreams or nightmares often, but usually nightmares more than dreams. And nightmares are the only ones I remember, because they loop, cycling between which one feels like playing that night. Sometimes new details are added, sometimes they remain unchanged. And on rare occasions, a new nightmare gets added to the rotation.
The worst are inappropriate for this site, but I can give some of the sillier ones. As a preface, I’m the sort of person whose subconscious is strong enough to hurt my body. If I had a dream or nightmare where I got burned, burns will appear on my body when I wake up. One of my most common nightmares is falling down the stairs. So while slipping on my heels and tumbling down the steps may seem tame, I’ll be beat up when I wake…Not that it will be long for that, I normally jump (quite literally) out of bed when I hit the bottom.
Then there’s giant ants attacking my house, destroying it completely, and killing my family. Usually they also attack me and I die, sometimes I can almost fight back, sometimes they taunt me with the dead.
