My problem with the traditional WILD is falling asleep. It is my problem for any technique after a WBTB. Often even for something as small as setting an intention. Insomnia (the fake one usually - the sleep state misperception) is my worst enemy. I am learning to know it and to manage it but I think it is a part of me and finding my ways around it may be better than trying to push through.
The other problem is the transition. Hypnagogia is easy. But going in and out of hypnagogia for an hour and a half with nothing more happening is frustrating (that's my record). When I feel that I am close, the anticipation begins to be too much, waking me up. The big downside is that it trains my brain to look for the signposts (and really, I am from the no signposts/ignoring the noise school, I just can't do it) and I can't sleep for the rest of the night, sometimes the night after that too, because I notice when I get very close to sleep. It really messes up with my sleep.
Because of this, I sometimes "wake up" into the vibrations, without even trying/wanting to WILD. I often have a dream body afterwards, sometimes I can move it a bit, but it is too unstable and I never manage to enter a dream. It always collapses very quickly. The best I was able to do was this - I was standing in our garden door and I sat down on a step there because I knew I had to transition slowly. And then I was thinking "What am I doing, I am already out of my bedroom" and then it collapsed and I was back in my bed.
I don't try it on purpose anymore, not after a WBTB, because I don't want to pay a day or two of insomnia for being able to move my dream body legs. I think with another 10 or 20 attempts, I would find my way through it but at the moment, I don't want to.

V-WILD is a way for me how to bypass all this. But I still feel like I have to trade off some self-awareness for being able to fall asleep and to get the visualization going. So I start with a completely conscious and controlled visualization (location in detail, senses) and then I let go off a bit and move to more daydreaming mode, letting my subconscious do the most of the work while being a sort of manager, steering it where I want. I like to interact with the imagined plot and talk to DCs - this really gets it going but the risk of losing all self-awareness is high. It is important not to analyze it or question it too early - when the subconscious does something but not everything, like the object on your footpath - it is not yet stable at that point. Better to question it 5 minutes into the dream than too soon. Or lost the self-awareness completely and regain it later. This makes it different from a fully conscious transition - it is not only almost impossible to tell where the daydream ends and the real dream starts, it is better not to even try to tell.

At the moment, I like to try 7 hours into my sleep to get the insomnia anxiety out of the way. I can be much relaxed when I am already rested and not too anxious to fall asleep.

No matter what it was, I am happy about that “WILD” I described in the first half of my first post. That one was without visualization but with strong intention to notice when the dream starts and the self-awareness checking in and letting go again every minute or two. I think it is more WILD than DILD when done this way, although it doesn’t fit the textbook definition.
It happened in a bonus sleep time, in the “snooze time”. I wake up, perfectly rested, but it’s still easy to go back to sleep almost instantly. I will certainly try to experiment with this timing more, it is risk free and I think it could work for me.
