One time I dreamt that one snake was trying to attack me. 

It was a cobra. 

I was in a cave and tried to run away from the snake. I ran very fast but the snake seemed to be just behind me all the time. It was as though it was flying and could bite me any moment. 

I quickly changed directions and went deeper into the cave, but there was no escape. 

Finally, I turned around and shouted at the snake with all my strength: 

BABA NAM KEVALAM !!! 

The snake disappeared and I felt relieved.
