Lonely Escape Cemetery

You fished at the bottom of the river and fell asleep for a fishing rod, and when awake, are trapped in an abandoned old cemetery with gravestones rickety, old family vault, similar to mini palaces. Place brings anguish and terror, would not want to stay here for the night, so take over the search for the key to the metal openwork gate, they are too high to climb. Overcome fear and look around, there are certainly hints.
