Well according to my family I talk in my sleep and apparently its quite bad.
I feel scared to go to sleep when in the same room as someone else because of what I might say,
What if i blurted out my inner secrets that no one but myself knows, It scares me so much, I hate it.

Its normally a very loud shouting outburst, like a swear word being shouted or something bad happening and me being angry I would be stressed, Its very rare for me to ever get that angry in real life but when I'm asleep its a different story.
Sometimes its just gibberish or a normal spoken sentence.

I feel quite alone with this problem and I need answers.
I want to know is this a rare commodity and how can I stop this happening?
