<P> When seen overlaid onto the physical world, this CEV noise does not obscure physical vision at all, and in fact is hard to notice if the visual field is highly patterned, complex, or in motion . When active observation is stopped, it is not obvious or noticeable, and seemingly disappears from normal physical perception . Individuals suffering from visual snow see similar noise but experience difficulty blocking it from conscious perception . </P> <P> Some mental control can be exerted over these closed - eye visualizations, but it usually requires a bit of relaxation and concentration to achieve . When properly relaxed it is possible to cause regions of intense black, bright white or even colors such as yellow, green, or pink to appear in the noise . These regions can span the entire visual field, but seem to be fleeting in nature . </P> <P> This level is relatively easily accessible to people who use psychedelic drugs such as LSD . However, it is also accessible to people involved in deep concentration for long periods of time . When lying down at night and closing the eyes, right before sleep the complex motion of these patterns can become directly visible without any great effort thanks to hypnagogic hallucination . The patterns themselves might resemble fractals . </P> <P> This is a fairly deep state . At this level, thoughts visually manifest as objects or environments . When this level is reached, the CEV noise seems to calm down and fade away, leaving behind an intense flat ordered blackness . The visual field becomes a sort of active space . A side component of this is the ability to feel motion when the eyes are closed . </P>
