2 questions. one regarding WILD, the other regarding a theory I have

[relV]

first of all,
Ive been giving lately attempts to the WILD technique.
When I lay down I see vague colors, shapes etc and every once in a while a whole scene kicks in as if im really in it followed with an intense vibration but after 1-2 seconds its gone, until the next one comes. I cant seem to maintain / enter those scenes.
Secondly
if you meditate during a lucid dream, isn't the dream environment supposed to change into the real astral reality?

I cant seem to maintain / enter those scenes.

I haven't Phased like this in awhile, so lets see if I remember...passively watch the images until one fills your entire viewing area. If your not sucked in automatically, just mentally push forward into the scene, focus on the scene or stretch your hand and grab something in the scene and pull yourself in.

I don't recall ever meditating during a Lucid Dream but if you go through a mirror it shoud take you to a random location on the Astral Plane.
