What do the morse code messages say?
SOS, LUCID MEMORY, T IS YOUR POSITION, SHADOW FORCES, VIRTUALLY INVISIBLE, DIGETAL INTERPRETATU, and RQ (or maybe YR if it’s looked at upside down). Some of the messages appear to be truncated or disappear as they go under a granite slab, so “T is your position” may be a portion of a message that says, “What is your position,” and “Digetal interpretatu” might be short for “digetal interpretation”. Please check here for some pictures or here for transcripts of the dots and dashes.
