I've tried calling out a specific person's name while walking around corners and opening doors but that method's only proven to be moderately successful. I've heard phone calls during lucids can be an effective method of "summoning" someone but I've never been able to find a phone during my dreams. One thing seems to work (for me at least) is trying to create a window/portal while reminding myself that I'm searching for X. I rarely remember to do this during lucids but the few times I've tried this technique, it's worked perfectly.

What techniques do you guys use when you're trying to find someone in particular?
