I dream while I am awake, too. But it doesn't feel as though my head will explode from pressure. I am usually sitting up and if a person is around, my body wants to interact so much that I start talking to that person with "dream words". Ex: my husband says, "do you want dinner?" and I say, "yeah, but first we need to put those rabbits back in the cage." There are no rabbits; this is in my dream. Since I never feel distress during this, I hadn't thought much of it. If you are feeling bad from this you should tell a medical doctor; you might have blood pressure issues, especially if changes occur when getting up or lying down. Good luck!
