My first experience occurred about 3 years ago, when I was 24. I was working at a facility for mentally disabled individuals where one of the residents had previously died. The people who worked the overnight shifts at my job used to tell stories about seeing the resident's ghost. I personally did not believe in ghosts prior to this.
3 years in I switched to the overnight position. A few months in, I was relaxing on the couch watching tv at approximately 3am. We usually settle down to nap ourselves around this time. Wide awake, I decided I'd give laying down a shot. I got up, turned off the light, and walked toward the couch.
When I sat on it, I instantly looked up at a shadow man that was hunched over peering at me. The second he saw I was looking at him, he turned and walked away. Frozen in fear, I knew what I had just witnessed was not my eyes playing tricks on me. After about 5 seconds of being petrified, I fumbled to open my phone and shine the flashlight where the man just stood. This man was short, around 5 foot 2 inches, and heavy set. Keep in mind, I had never met the man who previously died.
I was used to getting attacked by mental patients at that job, so my bravery was at an all-time high at that period in my life. Still scared, I peered into the kitchen where he was standing, and nobody was there. In fact, he walked toward a part of the kitchen that he wouldn't have been able to escape from.
I checked on my coworker, who was fast asleep on a couch in a different room. I didn't want to wake her, so I turned on all of the lights besides the one in her room, and laid down on my couch, wide awake and scared.
When she woke up, I told her what I had seen. The scary part was, I didn't even finish describing him, before she FINISHED describing him! That's when I knew that maybe those ghost stories were true after all. The one thing that she was surprised about though, was that he was hunched over.
I quit that job 2 months after this occurred, with this not being the primary reason but it pushed me to actually get a job in the field I wanted to work in (veterinary care).
Fast forward to yesterday. We are staying at my girlfriend's childhood home for the next week to celebrate Easter with her family. My girlfriend's father who was about the same height as the ghost I had seen 3 years ago had died before I met him. Well, it was late at night and I thought I may have seen a hunched over man in the hallway.
It happened quick, and I thought it may have been my eyes playing tricks on me. I didn't tell anyone because I wasn't sure that it was significant. This man wasn't close and it's quite possible it indeed was my eyes playing tricks on me.
HOWEVER. Just before writing this, I am sitting on their couch at 12:30am scrolling through social media. They have this mirror that peers into the room I'm in, and the light in my room shines directly at the mirror and glares back at me. Something just blocked the light long enough for it to flicker in my peripheral. Again, I'm HOPING that this was another trick, but this one put a good fear in me.
I'm just curious why they would both be hunched over when neither of them were hunched over before they passed away.
