Walking in to bed

Something that always freaked me out about old rpgs is the way you can walk right in to the beds. Its kinda hard to explain but everyone who has played an old school rpg should know what Im talking about. It looks like a normal bed but its somehow it must be magically standing up with the covers floating in front of it.

Thats the only “logical” explanation for how you can walk in under the sheets and come out on the other side without stopping , and please note the apostrophes around logical since the whole thing is certainly completely impossible and therefore highly illogical. Not only illogical but really freaky.
