Meh, don’t get caught up on feelings and HI. The thign I notice that happens a lot is people try to feel their body during WILD attempts. This puts more focus on your real body, making it harder to form a dream body. With HI, it seems that people get too caught up on trying to see the different shades and shapes. You just have to let the dream form! That’s all HI really is, images from your mind wandering and slowly forming into a dream.
You should really check out the VILD techinique. It can be found here. I think it’s actually easier than WILD and is based on a similar concept.
