“During our waking hours, we have the ‘id’ which says, ‘I want’, ‘I’m hungry’, ‘I want sex’, ‘I want comfort’, ‘I want warmth’ — it’s an animal drive,” Burke explains. “Then the ‘ego’ is what we think of ourselves: ‘I’m funny’, ‘I have a dark sense of humor’. And our ‘superego’ is the part of us that says ‘I should’ — such as ‘I should work hard’ or ‘I shouldn’t have dreams about having sex with that person.’ When we are asleep, it’s just the subconscious, it’s the bit that’s under all that and the id can be there: the desires and wants. It tends to be the level below.”
