Nyktolumos 

nyct-o-lu-mos noun: the faint, soft glow or illumination, emitted by turned-off electronic and smart devices in a completely dark room during nighttime.

It encompasses the subtle, often unnoticed cone-like beams of light produced by standby indicators, LEDs, monitors, or other low-power components present in modern electronic gadgets. This glow becomes more prominent over time as the eyes adjust to the darkness, making previously imperceptible light sources more noticeable.

Origin: The term "nyktolumos" is derived from the fusion of "nyx" (Greek for night) and "lumos" (Latin for light). It was coined to specifically describe the collective glow arising from electronic devices during nocturnal hours.

Usage: Nyktolumos can have varying intensities depending on the number and types of devices in the room. Examples of nyktolumos sources include standby lights on televisions, power indicator lights on chargers, glowing screens on laptops left in sleep mode, and the LEDs of smart home devices. This ambient glow, although subtle individually, can cumulatively contribute to light pollution and disrupt sleep quality in sensitive individuals. Taking measures to reduce nyktolumos, such as turning devices completely off or covering indicator lights, can be beneficial for promoting a restful sleep environment.

Additional Fact: Sometimes floating dust particles can create a 'sunbeam dust' kind of effect.

Surf Dracula Syndrome 

A phenomenon in film/television series, most notably streaming series, where the main premise is drawn out to such a point that it takes an entire season or more to get the parts of the series the audience is actually interested in seeing.

For example, if a series is titled "Surf Dracula," a majority of viewers would tune in expecting to see Dracula surfing by the first or second episode. However, the entire first season would instead be tedious padding and backstory before finally ending with Dracula surfing in the last five minutes of the season finale.
