I've yet to venture beyond "I'm still in reality, but it's distorted" territory (10mg freebase vaped direct via e-mesh, or a couple of long tokes on e-juice 600mg dissolved in 2ml in a sub ohm rig ) indoors sat in my comfy chair by the fire or outside with a good view ( vape juice is the most outdoor friendly delivery format IMHO).
I get visuals in the form of everything getting hyper sharp and clear, trees multiplying their branches and becoming impressionistic and moving when there is no wind, patterns forming on grass lawns. Plus occasionally certain things might suddenly get sort of "tagged as Significant" in my awareness, like you mention with the computer lights "looking at you", it's a strange feeling!
Faces can start to emerge and symmetries appear where there are none. But these are fleeting.
You can make the visuals more intense by looking at one area and not moving your eyes, they tend to "develop" over a few seconds and shifting attention will reset things. I find the speed of development a good judge of how far along the trip I am.
I see moving pattern overlays appearing on surfaces, faint at first, reminiscent of south american sacred art. interesting!
Closed eye stuff only becomes brighter and clear during the peak of the low dose trip for me, and will often take the form of geometric patterns and shapes with metallic lustre and checkerboard or motley style patterning in constant motion. Very fractally. I spent a lot of my youth programming fractals and ray tracings of hyper real things so that might influence what I see a bit. But it still feels like I'm looking at things behind my eyes, rather than "being in a room full of geometry".
Low doses certainly feel like they allow you to guide the experience somewhat, like an "imagination enhancer", you can spot something (an effect or feeling) and pay attention to it to enhance it.
I'm an engineer / science type (but with quite a strong arty streak) so maybe the urge to rationalise is strong and I tend to interpret visuals as "looking at" rather than "being in". It also might be why I hesitate to take larger doses so far, though I've fond memories of feeling completely in love with the universe on acid a few decades ago
The promise of transportation to "elsewhere" is fascinating and tempting, I will most likely continue upping the dose to see what happens.
Cheers,
