Dreaming

Ahh, Dr, Drew. What I wouldn't give to be thoroughly examined by you. You probably don't know much about dream interpretation, being an addiction specialist and all, but give this one a shot:
I'm looking into a large, empty room. The air is the consistency of TV snow and there is a distinct absense of color. In the center of the room sits a giant marshmallow that must be 30 feet high and at least 60 feet in diameter. A sewing needle, 10 feet long, suspended in midair, is slowly, deliberately being pushed into the marshmallow. The "skin" of the marshmallow resists, until finally the needle pierces it with a quick, painful popping sound.
When I wake, I am dizzy and disoriented. I cannot move for some time due to the overwhelming sense of pressure that forces my body into the mattress beneath me.
I believe the dream may be what is referred to as a hypnagogic hallucination, due to it always occurring at that stage where I'm between wake and sleep. It's always the same and leaves me feeling tense and slightly disturbed.
What could it possibly mean Doctor?
