Having Some Amazing Lucids

I've started getting back into lucid dreaming recently and have been as active as possible in my dream journal (about 2 - 3 entries a week currently)

I generally have trouble sleeping at night, it might be that my bed is getting uncomfortable, but I generally don't lucid during my first attempt at sleep for the night. After waking up however and going into my brothers bed (he leaves very early for work), after another few attempts at falling back asleep I've been having some amazing lucids.

I'm closing my eyes and when I open them I'm in the dream and it's an instantaneous realisation that I'm dreaming. I can't make this happen every time, but it's just as vivid as real life (there's none of that weird blurriness that happens a lot in dreams), like I've just been teleported to this world. Now these are the times I can really make an entry for the dream journal.

While I can do some cool mystical things in the dreams, it appears as if I don't have complete control and I can't truly do what I want. The most recent one ended when the inside rope of my pants had come undone and I couldn't tie them back up.

So what do you guys do for more control?

It's not so much how to have more control, as it is to have more lucidity. The more lucid you are, the higher chance you have of having better control. It's about how concious you are. It's not an easy thing to have full control, and I've yet to have full control. But just keep at it and eventually you'll be able to do anything you want and you won't end up with untied pants rope.
