i have also had this problem it feels like your on a set path your trying to fight with your dream trying to create but have forgotten how i have been unlucky with lucid dreaming i cant create dreams i can only barely control what i do but i feel heavy i cant speak and when i do i feel like iv stopped breathing though iv noticed one thing theres always a door open that waits for me when i see the door i realize im dreaming but when i try to go to the door i fear what happens if i try to stray from my dream i run into all sorts of nightmarish horrors horrors that would make anyone beg to wake up iv seen this door many times in my nightmares when i try to go to the door i feel heavy slow i feel like im being pulled back just last night i finally made it through the door i hope tonight i wont have another nightmare and i can dream word of warning there are things your mind can conjure up that you would wish you hadn't seen and i that there in that darkness this problubly has nothing to do with this im sorry but i hope what iv said somewhat sounds like what your running into
