Not knowing how to call an astral elevator, he took the stairs, stepping though the door that his hand could not touch. After a couple of flights, he realized he could not read the signs showing each floor’s number. He could see them and feel a sense of identity, but the words were gibberish. He should have counted landings. He began to stick his head through the doors at each landing, seeking the pattern of scars and debris that marked his own floor. It only took a couple of tries.
