I saw my soulmate from a distance in a cafe but he ran away before I could get his number/address/a piece of his shirt to smell at night. I drew him so if any of you see him, get in touch. This is me being sad because I get the feeling I’ll never see him again. :-/
Focus on the dream, focus on the details, picture them, feel them. The TARDIS will track on your subconscious and extract the relevant information. It should be able to home in on the moment in your timeline when you first had that dream.
