The retina can be made to produce light patterns of visual noise simply by one rubbing their eyes somewhat forcefully in a manner that increases intraocular pressure. Additionally, retinal noise can be produced by touching near the rear of the eyeball producing <a href="/wiki/Phosphene#Mechanical_stimulation" title="Phosphene">pressure phosphenes</a> (for example, if one closes one's eyes, looks all the way left, and lightly touches the rightmost part of the eye socket, this produces visual noise in the shape of a circle that appears at the left side of the visual field – a practice that is neither painful nor dangerous). None of these are closed-eye hallucinations, but rather the experience of mechanical stimuli distorted into visual stimuli.
