I think you just need to let go and be more involved in the dream, normally after we realise that it's a dream we go from "we're in a dream" to a "I'm dreaming" mentality, meaning that before we were actually within a dream world and then since we know that it's a dream and have an idea that we are actually in bed we stop seeing the dream as a place we are in and more as something we are watching and interacting with.

It's kinda like when you are watching a movie you can simply watch without getting involved or you can let go and for a moment you feel drawn into the movie.

Basically take some time to feel that you are wherever you are rather than treating it all as "just a dream" and start to control everything. Interact rather than take control.
