After my brother and I got seperate rooms, sometimes one of our beds would break and need fixing, forcing us to spend the night sharing a bed. We didn't mind, but apparently this had a subconscious effect.
After one broken/fixed bed then the other, sometimes we'd wake up to find ourselves sharing a bed in the morning without remembering getting up in the night. One morning, we each woke up alone in the other's bed.
