If you can see a rainbow you must have your back to the sun. If you don’t, you can’t see it. The only way to see a complete, full circle, rainbow is to be flying (or falling).

That debris includes dust mites (their droppings and their decaying bodies), mold, millions of dead skin cells, dandruff, animal and human hair, secretions, excretions, lint, pollen, dust, soil, sand and a lot of perspiration, of which the average person loses a quart per day. Good night!
