Dreaming of an Immune Christmas?

I had a dream last night where I was sitting in a fairly generic-looking government office (possibly a government library) when two people came in, wearing those day-glow yellow vests. One was carrying some sort of white and blue hand-held device. He said they were going around all the offices vaccinating people against Covid-19 and asked if I was interested.

I said I was, so he asked me to hold out an arm and then he held the device maybe six to eight inches away and pulled a lever or trigger of some sort. It let out a little beep and that was basically my vaccination - no needle, no fuss, no muss. Then the other person got me to sign a sheet of paper and add my PRI so they'd know not to approach me again (evidently it wasn't a two-dose vaccine?)

I think they then asked about who else was in the office today who might be wanting to get zapped as well, before moving on.

All a bit bizarre, but then many dreams are.
