Physical sensations in head on verge of a LD (WILDing)

[gab]

I always wanted to ask. Does anybody have physical sensations in head when just about entering a LD via WILD? I have a rather strong sensation in my brain. Top and back of the head, feels like something just turned on. Fizzing, almost bubbling, and sounds like when you put alka-seltzer in water. Not sure if I hear it or only imagine hearing it, or associating the sensation with familiar sound. But the sensation is there every time when less then 3 seconds from entering LD via WILD. When I feel that, I know I crossed the event horizon. Happy lucids

Interesting. Got something similar yesterday while dozing off during meditation before going to sleep. I felt a ringing sensation *in the center of the brain*. One of those things you can give a shape to: an oblique segment with transversal black and white stripes, the black ones being dominant.

I wish I got clear signs. I'm a poor WILDer, don't have it figured out yet, but the one thing that I think is constant to announce the coming of a dream is that I start seeing dreamlets, and sometimes start "seeing through my eyelids." I do get all-body buzzing/vibrating sensations sometimes, but I always fully wake up after them

They are very interesting. First I read about them I had no idea what they meant. I thought maybe the shapes a kinda saw in the "grey fog" were it. Then I saw the shapes and whoa, they are really geometric. Perfect squares, lines, triangles and whatnots. For me, always black and white. ... the one thing that I think is constant to announce the coming of a dream is that I start seeing dreamlets, and sometimes start "seeing through my eyelids."

They appear when you're in altered states of consciousness, most famously during psychedelic trips, but also occurring during hypnagogic episodes. They're actually caused by feedback loops in the occipital lobe, which is the area at the back of your brain that processes visual imagery. During normal (fully awake and sober) operation, you're not consciously aware of all the intermediate processing steps that are taken to get from raw optical nerve impulses to conscious recognition of objects in a visual field. But if this operation is interrupted or made "laggy" in some way, then you can witness the wacky world of half-processed visual data. And since the brain relies on feedback loops in its neural networks, the images you see are often either repeating shapes or fractals. This is just a consequence of the mathematics of systems with feedback. It's like what you get when you point a camera at a tv screen, but more complicated.

--- I saw it with my mind's eye. It's more like a mild form of synesthesia: sound -> shape. Another example is when you're trying to sleep and an unexpected noise causes a bright flash behind your eyelids: sound -> color. I saw a very complex hypnagogic pattern once though. Never happened again.

I noticed that when I focus on my body state during LD I feel a slight pressure somewhere in the back of my head. I even though about using this as an RC.

I get a strong "buzzing" feeling a couple of hours after having ingested Galantamine - a bit like feeling "pins and needles" inside the head. It is as if there is a kind of sound attached to it. I also associate it with WILDing.
