when i was younger i used to be scared SOOO much of burglaries, the dark, etc. BUT i started doing kirtan sohilaa every night and then i could feel a protection around me and i always used to have a peaceful sleep and i was never scared. Also, i had a doubt in my mind and i thought that i was sleeping so good just due to coincidence and that it wasn't anything to do with me doing kirtan sohilaa, so one night i never did it, and then that night i had nightmares, i couldn't get to sleep, i was sweating, it was horrible!
So it just goes to show that waheguru will protect you.
