Sometimes with our pets even with each other when we are laying down sleeping they feel they have to be more protective of us even with spouses for some reason. It is the same for me and my husband, if we are laying down and one of us goes near the other one our chihuahua wants to growl and come toward us as a protective method. It seems bad but that is their nature and I don't think it had to do with you personally it is just their protective nature, but you have to tru and curb that aggressiveness before it becomes worse. So without yelling or scolding and doing what you did putting him in time out will teach him that is wrong so he will learn not to do it, but that is just nature in some animals.
