Totally true story going back about 20 years when I was in my late 30s.
I was an acting assistant manager of a shop. We had this young Indian woman working with us, in her 20s and she absolutely terrified me! I think she scared other staff too but I was the only one who said anything about her.
She could speak reasonable English but would often try to talk to us in Indian. We had to politely keep explaining that we don't understand what she's saying and to speak only English when she's with us.
She was what I would call a psychic vampire - she literally sucked the energy out of us. She was devastatingly creepy, extremely moany, very odd, very lazy and tried to get us to do her work for her, never smiled, was seriously off. She was never in the shop, only working in the back.
When she wasn't there the rest of us were happy and laughing etc. but as soon as she walked in the atmosphere totally changed and became dark, eerie and ''sinister''.
On various occasions I had the misfortune of being left alone with her and each and every time, with or without other colleagues around, I could feel my knees buckling and I started shaking uncontrollably. I couldn't stand her.
It got to the point where one day she came in, again, creepy and negative. The manager was off duty that day. I shot into the loo and actually burst into fits of tears.
I rang the manager when she was at home and apologized for bothering her but explained the situation and that she'd been scaring us for the past month or so she'd been ''working'' there.
Manager said ''So it's not just me that's scared of her then?!'' This manager was known for being a nasty bully, loud and opinionated but as I was stood there on the phone actually crying and physically shaking she agreed to have a natter with The Vampire next time they're both in.
She did as she promised and The Vampire was a bit better over the next few days.
I left a few weeks later because of The Vampire and once saw her in the street. She tried to come over to talk, still looked and sounded scary but I made a run for it and refused to get anywhere near her! I genuinely believe she was actually evil and I had nightmares about her for weeks after.
