Had a few paranormal experiences but it was this one time back in the early 90s that always gets me. My girlfriend at the time lived with her mother in Heathfield Road, Wavertree way. The houses there are pretty old etc. They forwarned me that there was strange happenings at the house but I politely rebuffed the idea.
One of the apparently strange events was the sound of heavy footsteps running down the stairs. Anyway you guessed it. One night, me, my girlfriend and her mum are watching TV in the front room. Next thing I heard and felt heavy footseps running down the stairs followed by the front door slamming shut.
So we jump up and run into the hall and there's nobody there. The front door was locked as was the back door. Checked all the windows for entry/exit and again, nothing. I didn't sleep that night and it took me a good couple of months to go back there.
