How to make something pop up?

Hi! Im really having fun at lucid dreaming because I Got 3 times in a row
but my head hurts when i make something pop up i stare on an object uuhh like this :grrr: so is there anything easier??

U got to relax and just make it float, just think about slowly. It will appear. Like flyin, just think of flyin and u will fly. May not work but takes practice.

If you want an item, making it pop up may not be the best way to get it. If you imagine that item being behind the next door you open you will get better result i think.

Yea just looking like this :grrr:
will not help…

what you need to do is like WASD suggested think that itll be behind a door or what i always do is i imagine when i lift an object up itll be under it.
