strange visual effects of my room?

I shot you a quick PM - no problem at all with the video link. :)

hello, this happened to me as well a while ago. I know it's definitely not a dream or WILD process because I was also fully awake. Like Spock said, it's most likely HI-related image, but it still can't be fully explained with LD knowledge here alone.

I haven't found in your posts, but did you also experience that while even moving your head, the 'ghost image' of your room also moves according to your eyes? So basically it's like you're seeing your room moving your head around while eyes closed. It happened to me, I turned my head around, seeing the side of my desk and open my eyes - same image there. I know this can be a bit freaky to someone, but my best theory is as you practice LDing your awareness increases activating your 'pineal gland' or third eye, linked to remote viewing ability, so it's much easier to see something while in dark. (in fact it's easier to make HIs if your eyes don't receive external light at all along with the third eye) So some weak HI images can appear while eyes opened too. Actually third eye meditation naturally brings bright glow image while your eyes closed. (the white flash you mentioned)

This is all I can say from my experience and my dream partner, he experienced the same thing as well. I never thought it was that important(actually it's not important at all) as I thought I was just progressing with my awareness. So that means you're doing great. keep moving on :)

I agree with Spock, I think you're entering hypnagogia. I get it almost every night since I was a kid so I'm used to just observing it and don't use it to enter a LD, but I'm sure it can be used for this purpose.
It happened a few times that the scene I was seeing started expanding and getting more realistic and I've felt almost like I was entering it. I remember someone suggesting years ago that I imagine reaching out to that scene and trying to jump into this like you would jump into an imaginary painting or something,
If nothing else worked for you so far I would experiment with that because you're onto something here I think.
