Hmmm. I'm always so torn with this. I want to say that I don't believe in it, but there have been certain happenings that cause a spark in my curiosity and judgement.
When I was growing up, we lived in the house that my grandmother died in. My grandmother died of pancreatic cancer when I was 8 years old, but up until that age she was basically the one to raise me. I remember going to that house to visit her and each time she was significantly worse. I think the time she found out she had cancer to the point where she passed away was only about a 3 week period. We moved in to this house when I was 11 years old. I didn't notice anything right away, but when I was 13 really odd things started happening. Our kitchen was set up with two light switches, one on either side so you could flip on the light from one side and turn it off on the other. I remember, often around 11pm I'd go to get a drink and turn the switch on, almost immediately the light would shut off, so i'd switch it again and it'd turn on. This happened to me about 4 times the entire time I lived there and a few times it happened to my mother as well. However that could have easily been a wiring issue. Wiring issues are also connected to feeling the presence of someone, or the hairs on your neck standing up. So I usually pass those off. Another time when I was in bed I started to hear an odd sound, kind of like really loud water droplets falling in to an already filled sink... but with a really prominent echo. That was odd to me because even in the bathroom it didn't echo in such a way and I was significantly far from the bathroom. In that moment i got really cold and saw a quick flash of light. I tried to research it later and only came up with an explanation stating that sounds and colors can sometimes represent past energy that was left behind or a memory of some sort. but that doesn't seem right at all.
I've had a few other encounters with waking up to someone clearly calling my name but no one being home. It was only ever in that house. Since we have moved i have never experienced anything.
