The CRT afterglow was always a bit scary to me too, until one incident a few years ago.

One night I was trying to sleep but could not for some reason so I just was staring at the items in front of me, among which was an old Mac Classic (the one with an iPad-sized black CRT screen on the front for those not aware yet).

I saw it's screen is slightly lit so I thought it just went into screensaver mode and I forgot to turn it off, so I proceed to get up and walk to it, however it won't react to mouse or keyboard. I reach for the power switch on it's back and realize it's completely unplugged. Now that's when I almost shit myself.

Then a damn huge thunderstorm arrived shortly and I guessed that was the cause :-)

Not to mention phosphor oscilloscope tubes lighting up at night just because they were exposed to ambient light the whole day, or putting a bright skull image on your phone and letting it lay above the aforementioned Mac's screen or other tubes just to have it visible in the dark for the next half an hour to freak out random visitors lol
