I experienced this limit of flying a few times. I tried flying faster but it just didn’t work. Just like with a vehicle - you reach the max and that’s it.
What is that caused by? Is it just me being stuck with this reality’s limits, i.e. I can’t get rid of the illusion? Or perhaps it is the subconscious that can’t keep up creating new objects around me as I’m moving very fast?
Is anyone else experiencing this?
It makes sense to me to say that you’re stuck with reality. All it takes is practice practice and more practice.
Omg, when i was reading this post i remember that i had a lucid dream last night! 
i realised and then was about to try and power up like in dragonball z, but then got sucked out of my dream =[
i like held my arms up, ready to shout. then came out of it =[
Since when i fly i can fly fast enough to cross about 5 KM in 5 seconds, i don’t think it has anything to do with your subconscious, but more you’re too used to reality still.
I don’t think you’re limited by physical laws when you’re traveling in the astral. Try flying out into outer space, and see if you can fly fast enough to make the stars leave trails all around you as you pass them. If you can do this, you are already traveling WAY beyond the speed of light … which, according to the laws of relativity, is impossible for things in the physical plane (including light!). I think the astral body is something other than physical matter.
Actually, only if you believe it requires practice. The real trick is to expect the speed to be something ludicrious, and you’ll be travelling that fast. If you can’t break from your speed limit, do it anyway (if that makes sense).
I too think so. Maybe dreams are our imagination??? 
Or…it could be that a dream is a firing of nerve signals in the brain, and thus anything you can imagine will indeed become possible in the dream. (And sorry to correct ya, but stars wouldn’t leave trails, no matter how far beyond the speed of light you were going.)
Anyway, when I fly, I tend to run into altitude limits more than speed limits. I try to go higher up, but I feel like I’ve hit a ceiling. I think for both of us, our problems have to do with the fact that we have subconscious expectations of what we can’t do. I’ve never been above a certain altitude IRL; commercial airlines reach cruising altitude, but don’t go any higher, and even then I sometimes feel like I’m “too high up.” You’ve never gone faster than a certain speed, so going faster in a dream may be difficult for you to imagine. But you CAN do it, just like I CAN go higher! We just gotta remember that we can. Imagining a big burst of power coming out of your feet helps.
Speed limit through a capacity limit in the brain ? i higly doubt that you imagine so much that your “graphic card” would be under stress handling it 
A hint for flying faster : Imagine , for the practice a jetpack on your back and turn it to full boost , that should convince your subconscious (also known as yourself 
) that you CAN fly faster …
I’ve been able to achieve blinding speeds and cover large territories simply by levitating off the ground to a very high position in the sky, then fly across in sort of a bird’s eye view. If i fly as high as just say, a tree, I can still go fairly fast. However, if I need to travel across a much wider plain and at greater speeds, I first of all levitate off the ground to just below the clouds, then fly off in my desired direction. Have circled the earth and other planets several times in less than a minute this way.
I’ve always had so much ease when I fly…
Probably because after a while of that “swimming” type of flying, I figured out how to fly like Superman. After a few lucid dreams, I was flying so quickly.
I’ve hit that maximum speed - like you said, Eta - but I have so much control… It’s probably because I love to play videogames where the player can fly… and I play them all the time, I guess that counts as practice.
Perhaps you can play some games like that (even online games might work) and kind of get that way of flying stuck in your mind so when you try in your dream… it’s as easy as pushing a button!!
You know that’s a great idea actually! I will try some games where you can control a supersonic jet fighter or smth
