An approximation:

A man goes to his psychiatrist and says, “Doc, I keep having these alternating recurring dreams. First I’m a teepee; then I’m a wigwam; then I’m a teepee; then I’m a wigwam. It’s driving me crazy. What’s wrong with me?”

The doctor replies, “The first thing is to relax. You’re two tents.”
