Into the Catacombs!

You decide that a long walk wasn’t for you tonight. You would rather go and rest a bit before heading to the village. The place gave you the creeps, but you decided that it was the best course of action. You look around and approach the mausoleum, as you head to it the light slowly dims itself out. You find it odd but you still get to the door. You SLOWLY open the door, and as you step inside, a TON of bats start flying out! You cover your head from the bats, throwing yourself on the floor. After they pass you get back up and you can only see a dark corridor further, and a weird… thick goo on the floor.

What do you do now?
