Sometimes I get obsessive and think about the possibilities of things happening. I just make myself stop thinking about the scenarios. I can visualize people I love getting killed etc. I can stop on my own, if you are having problems you could try wearing a rubber band on your wrist and snapping it when the thoughts start. That might turn them off if you train yourself.

I read a great book on thought control called The Untethered Soul, it's by Michael Singer. Helped me get rid of unwanted thoughts. Gook Luck.

Sometimes I can switch them of. Usually not

Started doing it after my dad died then it got worse after a friend took her own life. All within the last year or so. Just constant day dreams of every possible outcome (good and bad) of what is going on in my life. After increasing one of my meds I have been doing better with it.

Are you talking about daydreams or intrusive thoughts. I have both. My daydreams are just mental masturbating. They range from being a form of not me doing something I could never do. My bipolar wouldn't allow it.

I was not James Bond because I could never be him. He is a fictional character. A superhero according to Family Feud.

Intrusive thoughts are usually associated with OCD. I have OCD. There are many kinds or variations of intrusive thoughts. They are usually uncontrollable awful thoughts that invade your thinking process. People do things to help keep them at bay. Mine was a ritual type of prayer done is a specific type of way or had to be done again and again. Others clean.

There are 4 basic intrusive thoughts. One is awful sexual from incestuous to beastliness., another is sacrilegious Godlike. I can't remember the other two.

I wish I cleaned but I do just barely. I bet my wife does also.

Cognitive Behavioral Therapy and medications help.

My intrusive thoughts lead to anxiety which leads to rumination which leads to depression.
