what happened in my lucid dream?

I had another lucid dream last night (well actually this morning) :banana::banana:

I have a few questions/issues:

1) At first I trying to fly and it was working pretty good, even though I didn't go very high. but later on all I could do was jump, I couldn't fly anymore. and I knew I was in a dream. how can I fix this?

2) I tried to turn invisible to see what would happen with the people around. It didn't work :( how can I do this? is there like a method?

3) one last thing I tried to was turn my pointed fingers into a gun :) I was thinking really hard about it and started to hear cocking noises but how could I shoot it? do I just think that I'm doing it :uhm:

OH and most importantly,
4) I knew I was in a dream, but it wasn't from a dream sign. I don't even know how. But it was still like a normal dream, for some reason nothing seemed wrong/out of place at all, but it was all wrong. And somehow I was lucid. I kept experimenting (with the things above) because I knew I was dreaming. What's up with this ?

Hehe, you're experiencing limitations in the dream.

Generally, you need some reason for stuff to happen, I'll give a few examples.

Flying: why can you fly? Try taking a pill that makes you have superpowers, and then fly.
Same with the invisibility.

Pointed fingers with a gun is wuite a cool idea too, but I dont know how to help.

How about, try to make a weapon appear instead. to make items appear, imagine it being behind an object/ behind you; basically out of sight, then go to fetch it.

Hope this helps, there are a number of threads explaining how to do certain things, but I'm new to the site.
