What does it mean to dream of being in bed with a guy you know?

Dreams are commonly your subconscious mind trying to sort out things from your waking life or situations.

Dancing in dreams is commonly interpreted as about the rhythm of life. Movement through time and situations. It also symbolizes happiness, celebration, freedom of movement and emotion.

Dancing with someone can mean a desire for a partner in life.

Freud, claimed all rhythmic movement was symbolic of intercourse, but not all dream analysis agree.
