What is this anime called?

Question

Me and my friend were talking about an Anime we saw when we were younger in the 90's.. I'd like to watch it again but I can't think of the title.

There are two girls who move to a farm/country.. there's a boy who tells them their house is haunted. They see these small black puff ball things at the staircase to the attack and the girl's grandmother tells them the black things are spirits. there's also a nice monster who the younger girl liked to sleep on top of.. I also remember a bus and rain and the girl's holding an umbrella? The little girl runs away and the older sister looks for her on her red bike in bare feet.

We think the title starts with a "W" ? If this rings any bells please reply!
