I did face something similar in my first lucid dream (after knowing what lucid dreams are of course)

in my case, several false awakenings got me lucid, but I still couldn't get out of bed because of the false awakenings

so I tried to fly my way out... well, it worked, but I lost lucidity instantly and the dream lost a bit of vividness
Hopefully I RCed and found out I was lucid again (getting lucid twice in a dream xD)
but it really happened to me


I guess the problem is not about dream dontrol, but about being too excited/putting too much effort on flying... As I usually say, dream control consists of watching the dream and changing the things you'd like to - not completely taking over the dream

but if you're still bad with dream control, try to daydream a bit... it helps a lot
And try to do hard things when daydreaming as well (like watching your feet moving as you walk, diving, digging, going through objects etc)

bear hugs
