Sucked into a dream...that sounds a lot like the early stages of a dream. It seems as if SSILD is good at getting your attention at the transitions into and out of dreams and that could be the reason that you notice more FAs.
Regarding your concerns about doing an RC and then forgetting your dreams, I am guessing that you are referring to moving to do an RC. In that case you can do a motionless RC. Let me know if you have any questions. :)
