I keep having the same dream, although some bits change the main dream is the same. I am always in a place that I am trying to get away from and I always have something in my mouth which is either choking me or stopping me from saying what I want to say!
I keep trying to get it out of my mouth but no matter how much I try I can't.
The stuff that is in my mouth is like lots and lots of string but thicker, but the other night it was a stone or shell and when I did manage to get it out of my mouth I opened it and there were lots of bugs in it.
What does it mean?

do you keep the thoughts you have had about people or a situation ,buried inside?
this isn,t a nice question ,but were you ever abused?
this dream could represent a behaviour that you are trying to get away from or a situation that you cant get over.

sometimes thru self-affirmation, a form of hypnosis, you can just 'will it away' by telling this sensation that it is past, it is over, and that you are free to speak your mind now...sounds silly but sit in a chair, in privacy, and focus on listeing to yourself saying this adn believe in YOURSELF and the pwoer to heal yourself.

2nd possibility is that there is some info/feeling form the past that is surfacing, could be as little as being to told to shut up as a kid over someting important..or worse, which, liek a nasty splinter or a glass sliver in a foot, is hard to find, causes pain all the time and is very hard to pindown and remove...which is where you could wind oup paying thousands in psychotherapy or hypnosis(cheaper) to unearth,..not always healing the wound. I like the first route, it is possible to 'get over it' without going thru the gruesome detials...you have to have the desire and will to free yourself of this crap.

Could be very little, but whateer it is is trying to come up...sit down and have a chat with yourself about this, and give your mind permission to consciously remember and discard as meaning less whichever event is triggering this. Take control of your feelings again.
