I wonder how much control we have of our dreams?

[No Vested Interest]

6. Before I was diagnosed with sleep apnea, I occasionally had dreams of a huge bomb falling,

similar to the one in Dr. Strangelove, though no one was riding the bomb in my dream.
I also had dreams of my teeth being loose in my jaws, ready to fall out.
Perhaps other odd ones I can't recall at present.

That was ca 15 years ago. I have used a C-PAP every night for ca 15 years and no longer have those dire-type dreams.
As a matter of fact, I no longer remember what I dream, though I may not be getting enough sleep each night (usually 61/2-7 hours.)
