I read about the Phillip experiment and it fascinated me. My housemate and I tried to replicate it, (created a fictional character called Harry bishop and would try to contact it) we would ask him to bring the remote to us, turn the light off etc, it kind of became an ongoing joke.
Then one night I was drunk and was calling Harry names, teasing him etc, dared him to show me a sign and I kid you not the door to my hallway creaked open slowly and my cat went mental, ever since then we made a pact to never talk about him, I’ve moved since and I’ve had another few strange things happen.
Not creepy but kind of cool. My mother split and transplanted a rose bush from my grandfather’s farm about 40 years ago. It took but never bloomed. At that point, she only kept it because it grew into the fence nicely and kept us kids from climbing it. My grandfather died about 5 years after she transplanted it and that spring it bloomed red roses. A few years after that my grandmother died and the spring after it bloomed white roses. These are the only two years it has ever bloomed.
