I suspect this: there is a permanent connection we have, as individuals, with the whole universe, through that common source that we call collective unconscious, anima mundi and otherwise. When our conscious bonds with the outside world are weak, we get closer to that connection.

You just got me going through my memories. I recall one of my friends asking me to shuffle a deck of cards, pull one out and put it on the wardrobe without looking at it. Then he went to sleep and the next morning he asked me (while still laying in bed, and yes I slept at his house) to check if the card was four of spades.

To my surprise it turns out that the card was indeed the four of spades. I couldn't believe him at first, but he told me that he had a camera in the room because of his sleepwalking. We checked it and he was in his bed the whole time.

I guess it would be improbable to randomly guess one out of 52 cards so I asked him and he said something like you before!

Btw, thank you for the tip and for such abundant comment! All the best!
