I did not know, that you could turn off the sound of a PC. But I needed Sim Tower to run overnight, to have enough money for the next floor the next day. That were some bad weeks without sleep as a ~11yo 😅

That "bing, bing" and the sound of the elevators the whole night.

Thankfully, it must have been all volts and no amps so I was OK, even though I let out quite the yelp. 😁

Complete myth. Please don't repeat this. It's not even remotely close to a generalisation, it's completely wrong and dangerous.

(Sorry, pet peeve of mine. Have had family members happy to play with mains wires but terrified to touch car batteries for fear of death)

100mA through someone can be harmless. 1mA through someone can be fatal. Lethal conditions occur under certain complex circumstances involving not just voltage/current, but frequency, exact waveforms, duration, contact points and the individual's physical parameters (human skin resistance varies a LOT, it's not an insignificant factor).

The most commonly encountered electrical hazards involve 50/60Hz 120/230V mains and hand/foot dermal contacts. This is a lethal combination that can cause heart fibrillation. Even 5mA or 100VAC can cause this (sometimes you will see lower numbers cited, "it depends"). Death can occur a day later, see immediate medical attention if you believe you have been shocked by mains wiring.

At very high frequencies our nervous system is not sensitive, so we can pass larger amounts of current or deal with higher voltages without much harm. I'll still hedge this with "it depends", you can get thermal burns (which if on the eyes includes blindness) and pathways through the body vary with contact points, changing the risks.

Static electricity discharges can be crazily high voltages and currents (many amps, sometimes hundreds of amps). Yet they are not a hazard.

The high voltages in your CRT will supply very high currents when applied to dermal contact points on the human body. This will likely induce involuntary muscle contraction. Prolonged contact could cause burns and unwanted chemical reactions to occur internally, but is unlikely to cause heart fibrillation because of the non-repeating DC nature.
