A guy goes to his psychiatrist . . .

And he tells him, "doc, something is wrong with me. Every night I fall asleep and I am awakened by one of two alternating dreams; one night I'm a teepee, and the next night I'm a wigwam. You gotta help me, doc, it's driving me crazy!"
The doctor thinks for a minute, then looks up at the man and says, "you're two tents."
