I was with some friends in a building of some sort. we were looking for things for some reason. we found them, and then the lights went out. i couldn't see a thing. Then I heard footsteps. They were getting louder. I tried to shout or something, but my voice failed me. I vividly remember the feeling of pure terror that i felt. It was the strongest emotion I have felt in a dream. Then, as the steps got louder, the lights came on. It was some harmless person that i can't remember because i think the shock woke me up. As a side note, I asked a friend of mine, and weird dreams like this could be linked to me trying to create a tulpa. which is cool i guess
