I saw a ghost

Hi.

I am a college student.

I am about to tell my story.

I think I saw a ghost at a classroom.

He was there.

Sat there a couple of seats away from me.

I thought he was just a student attending the same class as I am.

But I am sure i have never seen him before.

I felt this weird chills when I saw at him.

I realized that he was a ghost when he looked back at me and someone suddenly walked pass by him.

Like he was not there.

And he dissappeared.

I almost fainted and my heart beat so fast.

I got the realest goosebumps of my life.

I thought I was just imagining it or something.

But I was not.

I told my friends about it but they don't believe me.

:(
