I think the virus was a weapon, Used to take away more of our freedoms. Just like when 9/11 happened. Baby steps at a time to reach an goal at the end. Remember the 2012 NHS olympics opening ceremony? How weird it looked...
Think of it as 3000 years ago people doing ceremonies before the sacrifice.. Nothing has changed It's still the rich and powerful doing their weird magic shit. They have to act it out for it too manifest.
Watch it on YouTube. We got all the nurses dancing (much like how they was at the start of the pandemic) There was a Royal in the hospital bed (Boris? Charles?) You nannys coming down from the Sky with unbrella's that look like the corvid-19. They point the umbrellas at the Dr's who then went too the kids beds, Who was like get away from me too the DR's.. Death shows up bringing cats? And germs. Child catcher was taking away Children at the end (probably from all the dead) Then at the very end a giant baby was born... I think that represented a New Start.
I found it strange too.
After your description, I will have to watch it again.
Thanks!
