Hello!
I want to know how do you feel when you WILD and you are between the 2 world? This must be very nice! So, How did you feel?

Moved from Lucid Adventures.
Mostly relaxed 
More seriously, when I WILD I try to think up what my dream would be like, so I get pretty happy at the thought, then when HI becomes clearer, or the body more detached, then I focus more on the task, and only think of being aware and going with what happens, occasionally pulling things in the right direction.
It’s should be very cool! I guess the first time this must be really exciting
It’s kind of like watching a movie while going between the two, but I don’t really feel anything. It’s like fading off into nothingness while being a mere observer, but then the feeling gets reversed as the dream forms. I do start to get more and more disoriented as the dream takes over, and I usually have to dedicate the first minute or so to just trying to stabalize the dream.
My experience is similar to Rhewin’s.
Once the HI becomes clear it’s like watching a scene in a movie, then suddenly you’re in the scene. I always seem to periodically lose concentration and miss the transition, but different people seem to have different experiences.
Regardless, it’s pretty awesome. 
I have have a question : when you have HI, do you need to stand up like if you are in real life? What makes you know you’re in a dream?

In most cases, you just “are” in the dream, at one point. It all happens on its own, no need to move at all. You know because you’ve been watching those images for a while, and now you are inside those images
Along with what tosxy said, I also notice that I begin to feel things, as if I were there. While it’s HI it’s just images, but when I’m in the dream it surounds me and interacts with me.
OK
Thank for all your answer!
Will edit this post tomorrow after I have my first WILD (been trying for a while, but I have the attention span of a small newt) 
When I transition into a WILD, I’ll experience HI and sounds. It’s usually stuff that my brain has designed to wake me up, like my wife yelling at me to wake up, stuff crashing around me, my name being called, etc. If I successfully ignore it all my body will start to vibrate for a short amount of time. It is a very interesting feeling. After that I’m usually left with blackness which I can then turn into a LD. The first time this happened I didn’t know what to do and I hadn’t started with a plan about what to dream about. Randomly, the first dream I had was about some kind of gym class.
