yes, it is possible. However it is *very* difficult to enter WILD through it.

To see the imagery, search for the "visualization" channel in your mind. Pretty much scan your thoughts until you will be able to see random images in your mind's eye. That's not the HI, but observing that imagery helps you to reduce your awareness of your body and thoughts. After some time, if you stay focused you will be able to see genuine HI mix with those random images. Enjoy

As of now I dont see any benefit in achieving this state first time you hit the bed...
