Two nights ago I had my first "nightmare" in years. It wasn't scary as such, more confusing and disorientating, to a degree.It started with me in my garden, it was a normal day. I dont know exactly why I was in the garden, but there you go. I then looked towards the back of my garden, to see my shed door swinging back and forth, its a huge door and the inside of the shed looks like a massive black hole from where I was standing. I then randomly, out of nowhere, hear a piano play for a few seconds and a young boys voice laugh. I ran inside the house, scared, and locked the door, I stood at the window watching the shed door swing back and forth, trying to work out if it had any link to what just happened. I went into my front room and both my parents are sitting there. I said to my mum, who was on her laptop, "The weirdest thing just happened to me, I was in the garden and heard a random piano playing and a boys laughter"My mum then looks up from her laptop, with a blank expression and replies, speaking to my dad who was next to me, "Oh My God, that same thing happened to me the other day on my way to work, I think its that ghost"Then I woke up.Weird Stuff.
