When I was a child, I believed that if you had any body part other than your head out of the covers, T-Rex would walk by your house and see you and he would then proceed to lift the roof off like the lid to a box and eat you. He'd then calmly put the roof back down and keep going, looking for other kids to eat. Likewise, if you had an arm or leg hanging over the bed, something could reach up and grab you from underneath. Only safely in the middle of the bed with the covers pulled up to your chin were you safe!
