Well a few nights ago, I came the closest i've gotten to a WILD yet. I did what i usually did -watch the hypnogogic imagery, try to stay focused with a clear mind. After a while I felt like I wasn't focusing enough, so really started focusing - counted to 100, kept saying i'm dreaming, etc. and as I was doing this, my usual blue hypnogogic imagery turned red and my face started to tingle. After a few minutes of this I tried to 'pull away' my dream body and when i did it, i felt weird. I was still pulling away, but as I was pulling away, I felt like i didn't have any physical form, like i was a ghost. I then quickly came back and the imagery faded.
I guess one of my problems was not enough focusing or mental clarity.
