Travel to the past

You and your “friends” decide to go to an Egyptian museum to hang out, but they are not a very good influence, and they are not good for you, as they bully you. Whenever they see an opportunity, they don't take a second to play a joke on you, however, this time it has been worse. They have locked you up in a sarcophagus of the museum and gone. When you manage to get out of the sarcophagus by yourself, you find that you have travelled to the past, and now you are inside a hypogeum.

Will you be able to go to the future or will you stay in the past forever?
