Weird Graveyard event..

Ok, this is really random but creepy as fuck and might be interesting to read. I'm NOT promoting religion or anything just telling a story. So there is a graveyard close to my house. It is within a mile. I was coming home late last night and passing it. I saw a light coming from the woods line and almost like a tent made out of sheets. Also, I saw candle like lights coming from the inside. I live in a very small town with about a 5,000 person population. WTF are you doing back there??? Some of my other friends said that they have seen them there a lot. Fucking weird. My buddy and I might go check it out tonight cause I'm really curious.
