I do believe, sort of have to. Have to deal with apearences, sounds, voices, smells and sencing presence on a daily base.
Very good example was about 8 days ago when my little brother asked me if I came to sleep over on his room and when we where talking about anime's and manga someone tried to open the door, you know the sound of a door trying to open without lowering the lever. First tought was my mom who allready came in a few times to tell us to shut up and sleep. But the door didn't open and when asking "mom?" no responce. My brother said it happened all the time.
In my own room I hear people breathing, not like the wind but really breathing as in they are asleep. Sometimes a woman sings a cradle song.
