What is this peculiar mental state?

Okay, first off, it's been a while since I posted here (been having quite a few cool but still short DILDs meanwhile!)

Now the reason why I'm back is that last night I've been exploring a rather peculiar state of mind that occurs when I'm in bed. It happened often before, tends to happen when either I'm tired or I just woke.
When I lie in bed, I tend to think about things a lot. I'm never really able to clear my mind, I always need something to think about or I get bored as hell and then I can't sleep. Now, basically, what happens is, at some point it seems as though my subconscious sort of sneaks in, and continues thinking in my place, and seems to begin changing it into sort of a dreamlike thing. A few seconds after that begins, though, my clear awareness usually regains control, and I snap out of it.
This can happen in a rapid loop. Like yesterday it occured like, heck, every 1-2 minutes I think. So I thought I'd check it out in-depth this time, and managed to convince myself that, instead of snapping out of it, I just begin to observe those thoughts.

Now I thought, this must be the hypnagogic state of mind, but here's what puzzles me: the internet says that hypnagogia is supposed to induce meaningless, purely sensory experiences. Fact is, what I actually experience is the opposite of that, in fact during this state I seem to have a complete LACK of sensory experiences. I especially noticed that when I found out that, while I was observing that thought-dream, I wasn't even feeling my bed under me, so I tried feeling what's behind me, and suddenly my bed was back, as well as control over my thoughts.

So, tldr: this is a state where I have no sensory experiences whatsoever, including that I feel nothing, but it can't be sleep paralysis because I can cancel it at will by actively thinking or moving. The thoughts I have seem to be like a little dream, except that it's purely thoughts.

Any idea what this strange stuff is and, most importantly, can I use it to WILD? :D

it sounds to me like you have been getting some bad information on some of the terms like sleep paralysis and hypnagogic state of mind. i'm sure someone will point you to some good sources here for those topics along with WILD method. one thing though i will tell you about WILD is you probably won't have much luck if you're trying to induce it during your initial sleep time. works best with a wake back to bed routine.
good luck!

Welcome back!

To me, it sure sounds like HH. When your thoughts suddenly take life of their own and start developing into stories. It happens as we are fallling asleep, or even waking up and falling asleep again, in the inbetween state. Not awake, yet not asleep. It's normal not to feel our body or bed at this point. That just means that you are very relaxed. That is the way to WILD. To transfer our consciousness from physical world to dream world.

If you let these images develop by observing them, rather than trying to analyze or control them, they may form into a dream, that unravels in front of you, while you are still awake. That's when you can transfer yourself into the dream and be lucid.

Here is a WILD for beginners.
