Black mass

Today I had really weird, long and incoherent dream. The first thing I can recall from the plot is me strolling along some street, followed by one girl. I dont know why I remember her for she didn't even appear later. Anyway, then I found myself in some building, resembling my primary school, on a small feast. But the most important thing happend in the very end of my dream. I was putting my jacket on in order to leave the building when I spotted a creepy moth sitting on my shoe. I decided to spread it all over the floor but then a watchman came out of nowhere and started to remisce about him struggling the other day with enormous moth. According to his story, he applied a trick to slaughter poor insect, namely he used pincers and mashed it remorselessly. During our chat we were standing next to the front doors, which were ajar. Suddenly peculiar gust opened it wide, followed by glimmering light and dreadful murmur. We peeped out the frame and spotted a black mass taking place in the middle of the street! And the funny thing is that the leading satanist was the father of my ex-gf Anna.
