Is it normal to suddenly have the urge to hurt people i meet?
This has been happening most of my life, and it seems to trigger at complete random. The most vivid is in middle school I was having a conversation with my teacher and I happened to glance at a letter opener she left on her desk.
A bunch of images immediately played out in my head of me calmly picking it up and plunging it into her neck. By the time I processed just what was going through my head I had already picked up the letter opener without realizing it. I had to excuse myself to the restroom.
I'm in my 20s now and they continue to occur multiple times a week, with people, animals, and occasionally property. I've never actually acted on them, but I recently spooked a close friend of mine. Apparently my expression/demeanor changes when I have these episodes and they made a joke about getting me an exorcism.
Needless to say, I didn't find it very funny. Should I seek psychological help?
