I know the title is kind weird but sometimes my mind will focus on something disturbing. Example: When I'm driving on a moutain and I see a ledge I get a vision in my head of my car flying off.
or
I'll be talking to my friend's and an image of them doing naughty things will pop up... or even worse, like my brothers or my father.
or
Like when I hold my son I imagine droping him or worse things
or
When I went to my grandfathers funeral and I saw him laying here motionless a image in my head popped up of me hitting him with an AXE! AN AXE! like WTF?!
I'm pretty sure this isn't normal, right?
Obviously, you are not yet numb, so you need to protect yourself from the ubiquitous crap in the environment.
Turn off the ugly stuff on TV and the Net. Don't watch the news. Take up an uplifting hobby, like reading classic novels, of listening to classic music, opera, etc. Try bird watching, hiking in a natural environment, visiting art museums, etc. There is so much beauty in the world that doesn't make for compelling television.
As long as you don't have actual feelings like hate, anger building up while these images happen, and you know it isn't something your going to act on(Like while holding you son) it should be fine. Maybe you should see a therapist about it, because you don't want people to be scared of you when you tell them this is what's in your head. Or think it's one thing when really it's another.
Good luck.
Sometimes I wonder what the hell is up, but I think it is normal, just depending on how you think.
I've always had a very vivid imagination, and sort of a way of over-considering grim or extreme things in life.
I'm the person in the car who says, as we drive over a bridge, "Hey guys, wouldn't it suck if we all died right now?"
I'll have a vision of myself shattering a mirror, only to realize that that isn't going to happen and I don't have any true desire to do it.
Or I'll have a sudden vision/flash of violence or, as you said, a car flying off the road.
Seems pretty normal to ME, but then again... maybe we're both abnormal! :D
unfortunately there is not much you can do about it for now, just try to relax more.
Do something uplifting, something that will take yer mind off of this bad crap. Listen to happier music
