Making steady progress but could use more help

Although I've only been trying to WILD for the last two months, I'm happy to say that I have successfully had LD's in 5 of my last 7 attempts. Because I have been using supplements, and because I'm happy with having LD's only occasionally, I only try to WILD every five to seven days. I try to work on a different task each attempt and have had some success. One thing I seem to do frequently is walk or run through solid objects such as walls and unopened windows and doors. My biggest problem though has been getting clarity of the dreamscape, or expanding my view of it. I notice this especially when floating/flying or being high up on an object such as a roof or cliff. Could this be because of my sub-conscience dealing with my fear of heights? I have been rubbing my hands together and yelling "clarity" in my LD with only limited success. Any other suggestions?
