Hello ghostbud: I noticed this is your first post here on PC. So... welcome to Psych Central. I'm sorry I don't think I would have any suggestions as to the causes of the experiences you describe. Perhaps there will be other members, here on PC, who will have some thoughts they can offer.

I do, myself, have a tendency to say things out loud that I don't intend to say. Typically it's just 2 or 3 words. Sometimes it's related to something that's on my mind. Other times it's just words such as: "Oh well..." or "I don't know..." On occasion I have to quick come up with something else to follow up with that makes what I said initially sound like it makes sense. I've presumed that, in my case, this is related to anxiety. But I don't really know.

Anyway... I hope you find PC to be of benefit.
