are these symptoms of DP

I was just wondering if anyone else shares these symptoms...I'm sure they are part of DP but it would be helpful if there are others out there that share them.

- Talking seems weird. It feels as though its not me talking and I keep wondering how I know what I am going to say in each sentence and how I know what word follows the next one.

- My thoughts feel as though they have been amplified. They dont just drift normally. Each thought almost echoes in my head and I'm constantly aware of them.

- My thought almost feel as though they dont come from me. I know they do, but they feel as though they dont. If a random song or thought pops in my head I keep questioning "why did I think of that?" Which has turned into an obsession in itself because whenever I think of something random I question where it comes from.

I also seem to have an obsession about questioning the workings of my brain. If I know the answer to something I keep questioning HOW did I know the answer etc etc (which is really getting very tiresome!)

Thanks for replying
