Druids?

So hi, my name is Luke and I'm 13 (a little young). I suppose you have seen the title of my story.

It all started in school in the bathrooms. I was taking a wee when in the distance behind me in the cubicle I heard my name like a faint "Luke...Luke!" I turned my head swiftly to see a strange hooded figure walking out of the cubicle. It was a druid from what I saw. It was dressed in all black, its face was completely black no facial features. It had its sleeves tucked in each other. (By the way nobody else was here at the time). I ran. As I did I heard it say something which I thought was some ancient language so I continued running and as I turned, the door slammed. But that's not the end...

My friend (not my friend no longer) had an interesting experience too.

He was in the cubicle when he heard footsteps and the door was shaking and a voice shouted, "I'm Going to Get you!" He was frightened to the bone, and then it left.

Next is one of my own again. I was sitting in class when I look at the door (which has a mini-window on it). I saw the face of an old looking woman who just knocked and looked at me and smiled. I nudged the person beside me and asked him did he see that and he said "no".

Then again wherever I went after that I would never feel alone even when I was. Footsteps followed me when I was alone.

Then I was in the bathrooms once again when I was on my way out when I heard a cackling laugh and out of nowhere I feel light-headed and collapsed when a voice in my head says, "You don't understand this" and I get back up.

Later that night in my sleep I remember the face of the woman and the druid. The woman was standing in front of me and around me were Druids beating drums chanting the words I had heard the druid earlier that week say. I haven't heard any thing since.

Can any one help me and also thanks for reading (and I don't think this is me being crazy).

Peace!
