Maybe the stairs are just more noticable because of noise. Stairs in general usually have a distinct "step sound" and people may think "who is walking up the stairs?" then see no one or a ghost. Some stairs may be haunted specifically if a person fell down them and passed away but also might be a hot spot for residual hauntings because going up and down stairs is more significant than just walking around the house.

I used to be afraid of staircases when I was a child. There wasn't any proper lighting and almost always, the fear of the unknown increased as the staircases were dark. Quite a number of accidents also took place, especially when beings trip and stumble, or were deliberately pushed down the stairs. In extreme cases, death was the final result.

I thought this video would be of help. It is interesting!

Why don't you just conduct a seance and ask the spirits. Like, directly. Just a suggestion.

summoning the dead is a great idea however if your not familiar and can not control it can be a bad idea i suggest next time do a protection border and to get rid of your problem you have at the moment start with the rock salt at the entrance of your house inside go all the way around till you have completed every inch it will push out what ever negative spirit that may be lurking the burn some sage around the house to get rid of the negative energy you can also do this with your body to be cleansed like the rock salt during a bath and the sage to get rid of any negative energy

to answer the question in my belief after doing my own reading it is considered a border line much like the say a little rip in a certain area its a cross over just like they say the stair way to heaven to get to another or i'm sure you have heard of a black hole in some areas its just considered a rip many different way of explaining it though
