Can obsessive thoughts be like how you would image an apple in your head but they are not controllable? How does that differ from hallucinations? My understanding is that hallucinations are visual things that are added through your eyes and not in your thought imaging that you cannot control.
Obsessive means the thoughts recur and trouble you.
Intrusive thoughts come against your will and trouble you.
Hallucinations are any of the 5 senses activated when nothing is there.
Can these thoughts be imaginative people talking in your head or is that hallucinations?
