Is this a Normal thing?

As i got better at lucid dreaming i started to notice that When i become Lucid in dreams my dreams will instantly start to fall apart and i have to quickly stabilize it. and if i fail to, i will fall through this blackness and end up back in my room on my bed. Normally, They turn into FA's. As im getting better though, I can retain my lucidity through the fall to my room. whats annoying though is why do dreams try to trick you into losing your lucidity? :( Do lucids normally turn into FAs if you cant stabilize them?

When your dream fades, you either get into a FA but can wake up in your bed too...When that happen, I simply DEILD and come back in the dream I was...
Simply don't focus on the fact that you lose lucidity or I think you could create a block.
