How to I "create" something in LD

How do I properly do this?
In today's LD, as soon as I became aware, I was trying to summon a person of my choice and after first try, I failed to summon anything xD
Second time I attempted, fail again. And third time, I kept my eyes closed for few secs, shaped the person and when I wanted to open 'em, I just couldn't open them for a few secs. When I managed to open 'em finally, there were couple of people behind me that looked nothing like I imagined xD

So, I just let it go and went jumping really, really far
Any Advices?

There's a bunch of good techniques for dream character summoning. Have you tried turning around and expecting them to be behind you? Or you could try reaching behind you and grabbing the person's hand. Calling out for them. You can ask a DC where the person is, that's one I really like. Some people go to places where they would expect that person to be. Narrating what you're doing also works, say things like "I'm going to go meet x" or "x is in the next room"

Good luck! (^o^)b

Oh, those're some nice things I could do :D
Thanks for pointing them out

I haven't had a lot of luck summoning specific people, but the other night i was successful in falling asleep thinking about the person and then they were in the dream. So induction can also be tried.

I still haven't had any luck with conscious incubation, but I really want it to work.

But I have also thought about acting all bossy and telling whichever DC is already there, "You can tell [summonee] that I'm ready to see her now." :)

Try finding a door and believing 100% that there will be someone behind the door (being more specific and trying to recall what they look like might help), it worked for me in my first ever LD after practicing for about a month and a half.

I would recommend that you summon them in ways that feel somewhat realistic from your waking life experience.
Expecting someone or something to just appear out of nowhere in thin air is obviously very unnatural in our waking life experiences, so it would probably be much more effective to expect something to be around a corner or something.
Or if you want to meet a certain person, try walking over to their house.
