Reality is but a depiction of the mind that makes little sense and is only true if you allow it to be. It only follows along certain rules and guidelines as long as you want it too, and then you may open another door to another reality once you grow bored with this one.
Dreams are but tricks of the mind and makes little sense but for a moment causes something akin to happiness and peace. Then, when you wake, you have a 'I wish it were true' moment even if you don't remember the dream.
This is my reality, and you're trespassing. But please, feel free to feel welcome, but I don't recommend taking anything from the butler; he tends to favor arsenic. Don't lock yourself in a room, the maid likes setting things aflame. Oh, wait, since they're both in my mind, that means I'm the one who favors arsenic and flames....
