First Lucid and Questions About Control

Hello After many months trying I had my first fully lucid dream around 6-9, I used the wbtb method.Because of being unsuccesful in the past I couldn't really accept that I was lucid at first. But I did become lucid and loved it :D

I just have few questions:

1. I attempted to fly and I could get in the air but I could only move really slowly and everything was blurry. Any tips on flight?

2. I also atempted to run fast, like sonic, so that i could get to places quicker. i did it once for a short distence but couldn't do it again :(

3. any advice on summoning people you know?

Congrats. Running fast isn't a good idea at first, your brain needs to struggle to keep up with imagery at that speed, it's like a computer, it has a speed limit. I use my arms like wings to fly, try that.
