Help for old film identification (possibly 80s)

[filmmusic]

Hello.
I'm searching for a film that I had seen in my childhood but unfortunately don't know what it was.
Also, unfortuantely I don't have many clues except for this:

I think Faye Dunaway was in it (i"m not 100% sure), and at night when she was sleeping she was hearing voices, someone talking to her (another woman).
And from what I remember I think it was someone hidden under her bed or something, and they were trying to make her mad..

Does this say anything to anyone?


Also, the film is possibly from the 80s, or 70s. (it's not Laura Mars although I haven't seen it for years, but did it have a scene like that?)
It's definitely not from 1990 and on.
