Wasn't at the Stanley last month but I've been following reports from that place for years and the bathroom stuff keeps coming up over and over again. Room 217 gets all the attention but honestly the reports from the communal bathrooms on certain floors are way more consistent if you actually dig through the older accounts.
What did you feel exactly? Cold spot, pressure, something else? Because there's a difference between "ooh spooky hotel atmosphere" and actually experiencing something you can't explain. I'm naturally skeptical about a lot of this stuff even though I'm here, so I always want the specific details rather than just vibes.
Not dismissing you at all, genuinely curious. The Stanley has too many independent reports to just wave it all away.
