I have been to Pennhurst with a group of friends. One minute I knew we were together down in the tunnels but I looked around me no one was with me at all. I was by myself at that point.
I decided to go into a building of course didn't know which one. I went into Quaker building (which is the darkest building you would ever walk in). I entered and I was ok. I felt calm and relaxed, next thing I know I had fear rushing over me (like a sugar rush). I knew the entities that are in Quaker. I tried many ways to get rid of the fear. I blinked my eyes and took a deep breath, after that I got back to normal. Maybe 5-10ft in front of me I could make out four sets of glowing red eyes.
I do know in the basement of Mayflower building there is an angry doctor who likes to throw tools or other objects. But in Quaker I really thought my eyes were playing tricks on me but one of my friends found me and she saw the same thing and I did blink again. In that moment I asked about 10 questions before the four sets of glowing red eyes.
In my honest opinion Pennhurst is 100% haunted. I have talked to my friends and they say "Pennhurst is extremely haunted". In my own opinion I believe each of the buildings have their own pulse and function. Quaker in my opinion is the darkest building out of all over 20 buildings.
Pennhurst has 112 acres of land, and was originally known as the Eastern Pennsylvania State Institution for the Feeble-Minded and Epileptic which then got renamed to Pennhurst State School and Hospital and its been that way for years. Here's a history note: Eastern Pennsylvania State Institution was built in 1908 and closed in 1986, there were at least 3,350. Way back in the 1950s.
