So it's been a while since it happened and I remembered now, after I came back after defeating the gargoyles, I decided to get the goodies I forgot to get in the cemetery area. I went towards the pool/flooded area below the giant crow and a loud snoring sound rung out. I had a look around but couldn't seem to find where it came from, the crow was awake like usual.
Can anyone explain this? I'm a little bit curious.
