My thought processes feel unreal!

Does this happen with dp?

My thoughts feel unreal and confused. I keep wondering how thoughts happen and how they are processed.
Mine feel as though they are coming from somewhere else. Its so hard to explain and difficult to stop obsessing about.
When this happens it makes me panic and I cant stop trying to work out why it feels like this.

I have managed to stop fearing the unreality outside of myself and the detached feelings, but the thought thing is still scaing me.

How can I tell myself not to be afraid when my thoughts dont feel like they are mine or happening normally.

Does this make sense to anyone.
Im so scared I will disappear inside my own though cycle and never come out again.

Can anyone give me any reassurance.....please
