Gallan is someone you meet in dreams, but few weeks later you accidentally meet him in your garden, he is walking around as if he lives in your house.

You were surprised and walked up to him, "Who are you? Why are you in my house?" You ask confused.

He turned and put on a confused face and answered. "This is my house, I'm having a party with these people" He replied as if there's bunch of people around us having a party, but I only saw the two of us.
