You are Travelling to and you went to a Pyramid to learn the history,you explore more and you find a big snake statue,its really big

You continue walking,when you are walking you see the statue slightly moving,you try to think its just Hallucinations,you went to a room, suddenly you feel someone behind you

You turn back and see a big man towering you,he is like 225cm tall,his skin is grey "a human?" he said in annoyed tone,and he has big snake on his shoulder,it hisses at you
