question about "The Shining"

[Ryanwb]

Okay I have seen this movie like 100 times since I was a kid, and there is one scene that never sat well with me. The scene is when Shelly Duval comes up stairs and there is a guy in a bunny (or bear) costume on his knees between the legs of another person.

Ever since I was like 9 years old I have asked allowed "WTF is that?"

Can anyone tell me what that is?

According to filmsite.org:

Driven to madness herself, Wendy rushes upstairs looking for Danny. She hears echoes of chanting. Through one of the hotel room's open bedroom doors, she catches a disturbing, perplexing glimpse of a sexually perverse scene from the hotel's sordid past - another piece of evidence proving the entire family's possession of the 'shining' phenomenon. A man in a dog (or bear) outfit (with a open bottom) that masks his face, possibly a guest who has wandered up from one of the hotel's ancient costume balls, is stretched out over a formally-dressed male lover on a bed. The decadent sexual act of ******** between the participants is interrupted - they look up and stare back at Wendy.
