Our brain is telling us it needs to replenish its supply of chemicals and hormones. When you lay in the bed or on the couch, you're more relaxed and you feel sleepy, but when you're on the computer playing TF2 or Far Cry, you're doing something that requires energy, and you have some energy left until your body calls it quits, and you subconsciously end up in your bed.
