There's one main problem with bed alignment and that is that 'safe from demon's' and'safe from spiders' are on OPOSITE sides of the spectrum.
You've got a bed against the wall? Demon's can get you from 3 angles and spiders get 1. Beds against 2 walls? Demon's 2, spiders 2. Your beds in the middle of the room? Safe from spiders but demon's have free reign; though if you do that clearly an absolute heathen and fear nothing(except spiders) so you should be good anyway.
Point is the two most terrifying parts of bed placement collaborate to create an inescapable vassel of fear in your bedroom and that's a problem.
