I'm inside your house and always have been.
In the day i'm usually perpendicular to you but in the night parallel to you.
You rarely think about me but use me daily - you even have to!
I'm five letters long.

Perpendicular to you during the day, when you are upright, and walking around. Parallel to you at night when you are lying down in bed.
You have to use it to move around your house (unless you can float), but don't really think about it.
