I don't know how to categorize this because I've never heard of it. This has gone on for 25 years or more. It mostly happens when I am waking up in the morning and not really dreaming, but just letting my mind wander. It happens mostly then, but can happen at any time of the day or night if I happen to be daydreaming. Here goes:

If I daydream or picture myself in ANY situation, there will be immediate danger involved. I could imagine myself standing on the sidewalk and immediately the cement could go out from under me and I fall into the ground. I could imagine myself running a power saw and immediately I thrust my hand into the blade. I made those two examples up, because at this time I can't even think of a good example. However, when it happens, it is immediate, quick, completely out of my control and persistent. In my slumber or even awake, I will jolt myself out of the situation. I have even found myself saying STOP to myself. It snaps me out of it for the moment. I have gone so far as to tell myself, this is only my imagination and in my daydream or slumber, go ahead and stick my hand in the saw. Nothing happens of course, it's just my imagination, and it's almost like it takes the power away from whatever is causing this. if I do "stick my hand in the saw" or jump off the building, or allow myself to be sucked down into a crevasse, I don't feel happy or sad, just resigned to the thought that, "okay, brain, you won, now leave me alone".

I don't have a history of mental health issues and I feel like I'm about as mentally healthy as the next guy. I am not a drug user and I haven't had alcohol in almost 20 years (personal decision). The only medicine I take is a beta blocker. I do drink a lot of coffee but I'm trying to roll that back in the afternoon because it does affect my sleep. I'm happily married and financially stable. If I believed in demons, I'd say it was a demon pushing me into these situations....but I don't believe in demons.

This is not a problem that is affecting my daily life, I just don't know why these racing thoughts keep happening.
