Am I Some Sort of Medium?

by Hazel

For the past few months I've been seeing little movements, in different colours like white and black. They're like insects, moths or something, flying in front of my eyes, but when I focus in on it it disappears. I sometimes get random sentences in my head from nowhere, things that don't make sense; like personal jokes from someone. The more I consider that I can see ghosts the stronger the movements get and its annoying me. A lot.

Please can someone help? I really need to know if I'm a medium or something like that.
