Dream meanning?? explain as best as you can?

I have been having this dream for months now im on top of a building its storming. I am with another person who is wearing a mask that has weird red glowing jagged lines on it. so We begin to fight each other sometimes we have weapons (mostly swords) the person is covered in weird armour i guess. so we fight for a long time and when i take off the mask its my face and it starts laughing and then the dream ends. can you tell me what this means and be serious!!!!!!!!!
