Did anyone else see shadow figures at the old Waverly Hills Sanatorium last weekend?

Didn't make it to Waverly Hills myself but I've been obsessed with that place for ages, I nearly booked a trip last year but couldn't get the time off work. Really want to hear what you experienced though - were the figures solid looking or more like a dark mist type thing? I ask because I went to a supposedly haunted Victorian mill here in Leeds a few months back and caught what looked like a dark shape moving near one of the old doorways. Couldn't explain it at the time. My mate thought I was daft but it was clear as anything on my torch. Wondering if its similar to what you saw? Would love to compare notes because shadow figures seem to come up so often in these places and I'm trying to work out if theres a pattern to where they appear - like certain rooms, certain times of night etc. Anyone else who was on that Waverly visit please chip in too.
