[S3E16] Biggest detail of Audrey's scene noone's mentioning

So the coma theory, or the psych ward/hospital theory are being peddled as near fact in these threads, and I don't buy it.

Why?

Cause the music at the very end of the episode - a continuation of "Audrey's Dance" - is playing in reverse. Wouldn't that imply she is in some Lodge/extradimensional space? Seems like a pretty BIG detail for fans to just ignore. Backwards sounds in T.P. always imply the lodges/other places.
