When John awoke on the first day; someone had been dreaming of his other lives - specifically this face and by complete accident shapeshifted into that face - which lead to a very panicky Mr. Smith - which was soon to follow with him catching on fire but also not being in pain - which leads to him rolling on the floor and putting out his fire.

He needs help because this is impossible! And complete madness!

So, with his usual dress suit and pants; leaves his room with a face after all this is a dream but not a dream.

Maybe his dreams really are real!
