It was happened to me once ... We were staying late for night studies in my school time and friends decided to have midnight dinner... We all went out and had a great dinner... when we were returning to our hostel, we saw someone in white curtain coming towards us... We were scared and immediately ran away from there... we somehow reached hostel and then came to know that the guy who was wearing white curtain was our senior They came to know our plan to leave for dinner and planned to scare us...

Remembering that time I still piss in my pants
