I can't see or hear a lot of my companions at the moment. Could be because I'm starting to get back practicing sexual magic, what changes the own energy levels and starting to get into shadow work at the same time. Or the thought forms I'm struggling with are blocking everything.
Shufflemancy is using a playlist of songs on your phone or computer (the bigger the better, for a variety of possible answers) and instructing the companion you want to talk to with what you are doing, so they can use a song as answer. Like you say: "I'm skipping three times in this list, so please let the third song be your answer."
Sometimes you have to guess, sometimes it needs more than one song, but often enough the message can be crystal clear.
Like my woodland fae picked a song, that was literally about her trying to talk to me and me not hearing her.
My gryphon picked a song to let me know, that she's sad we can't communicate right now and feels a bit lonely and hopes things will change soon.
