I wanted to say that I didn't know about this technique when I had this strange but simple experience

I was trying to WILD. But my mind was so fluffy I didn't even remember that I was trying to WILD. All of a sudden I had this very strange premonition of what was about to happen to me! And I tell myself "I'm about to sink under my bed". I wasn't excited or scared, it was just a matter of fact! I'm about to sink.....

I take a deep breath as if I'm about to submerge in water. And when I exhale, that's when the shift into the dreaming took place! Just right there in that breath! And it sorta felt like...I fell underneath my bed into a pool of water. It felt like water because everything felt thicker, slower, and sound was muted.

I sink under my bed, through my bed, and shifted through this watery consistency for only a brief moment before landing softly on my new dream bed! Where I was aware that this was a false awakening. I think it's cool how similar my experience was to your tutorial even though I hadn't read it before! Did you experience something similar to come up with this idea?

Have other people 'sunk' beneath their beds into a dream before this tutorial?

I really want to repeat this experience!! But I'm worried. I have no idea what type of consciousness I was in when I did this. I mean, I knew I was about to shift into the dream, but I had no expectations of anything. Usually when I'm trying to WILD, or even close to entering a dream, I'm excited! I find being excited ruins it though!

I like this technique of yours though. Since its technically a VILD, I don't have to be so anxious about dream entry and I can just get lost in my imagination instead!
