Do you think this would work? What I am saying is that when you realise you are dreaming and want to make someone/something appear, you tell yourself that you don't want them to appear and that you hope they are not around the next corner and that you are scared of them. You know how in dreams if you expect something scary to happen it often does? Well same principle. You make yourself believe you are scared of something happening (which you actually want to happen) and then it would hopefully happen.

Do you think it would work? I know it sounds kinda confusing. I've not had a lucid recently so not had a chance to try it out, but I thought if someone had problems controlling their dreams they could try this.

For example- (Lucid dreaming) "I really hope my crush doesn't show up because I'd be really embarassed and scared of him/her, I hope they're not around the next corner..." (Then hopefully they would be)

I'm just thinking aloud so it probably sounds like a dumb idea!
