I've had many experiences. In one, I bought a new house. I had a feeling that there were some energies/entities there. The first night I was not able to sleep. In a state between awake/sleep, someone grabbed my hand, I asked them to let me sleep. I could see the image. A middle-aged white, blonde man. He introduced himself as Simon. He told me a year and he repeated "spineless, spineless, spineless"! I was shocked.

In another case, I had a dream that something like a bus stopped at the road near to our place and a naked and transparent man was dropped laying down on the ground. Then on the same night or the next one, my son woke me up saying there is a ghost sitting on his computer chair. He said suddenly his room got extremely cold and he could see this figure sitting on the chair. When I went to his room, I couldn't see anything but the ghost kept making noises, walking noisily like was wearing slippers. I had to ask him firmly and loudly to leave. After a while apparently he did.

In another case, an upset ghost entered my apartment from balcony. I was on the way, I heard him say telepathically " clear my way, I'm not in a good mood today!"
