i’ve been doing this for a couple of weeks and i’ve been able to get my structuring and visualizing up from around 15 seconds to over 2 minutes, which surprised me. but that’s cos i do it pretty much every day. at first it gave me a feeling like something was tapping really hard on my forehead and the tickling of the ant feeling like something is crawling around on the inside of my forehead and around my eyes. then after a couple of days i got splitting headaches. now what i get is a feeling of pressure on my forehead - strangely enough i even feel it right now as i’m typing this. all of those things have been accompanied by some very lucid dreams at night, almost like wandering around on the astral, just going everywhere in general and nowhere in particular.
you have to just work at it, there’s no way around that. it happens slowly but surely so keep at it.
