The discussion centers around the observation of air particles appearing to flow from a fluorescent lamp, resembling a waterfall effect. Participants note that changing to a different type of light bulb can alter air circulation patterns, which may affect how these particles are perceived. Some contributors suggest that what is being seen could be related to "closed eye hallucinations" (CEH) or floaters in the eye, while others describe a similar phenomenon of seeing static-like particles in the air, especially in low light conditions. The conversation highlights that many people may experience this visual effect to varying degrees, though it often goes unremarked upon. Some participants express curiosity about the nature of these observations and consider consulting an optometrist for further insight. Overall, the thread emphasizes the commonality of these visual experiences and the importance of clear communication in discussing them.
