Runaways DJ

I read about technique to go to someone else dream. In dream you need to have mirror and DC of person which you want to go in dream. Then you set this DC to see him in the mirror and then go through it. It's required to have specific feel to work.

I'm lucid in my room. I screaming PS. No one comes, so I thought I do something wrong. I start screaming to see DC of PS. Then someone comes, he was mature man with neat black hairs, beard and pale face. I set him near the window (my mirror), when I saw him I jump through window. I was falling into the black hole and I woke up.

I don't have that specific feel and I don't know how PS look like. I gonna try it again, but with friend I know IRL.
