Dark Sanity (1982) 
Dark Sanity concerns a recovering alcoholic and her husband who move into a new house which was the scene of a grisly murder some years before. The wife starts seeing visions of the murder and the murderer via psychic visions, to which everyone else attributes to a relapse in her drinking. However, an ex-police sergeant also shares this particular gift (conveniently) plus believes that the real killer is still at large.
A pretty ropey and inconsistent film that seemed to crawl along and then run out of steam a little at the end. Supposedly a slasher, although I wouldn't exactly classify it as such.
Name change suggestion: Dull Insanity.
