A falling fairy

Now that I know for sure that they exist I can share my experience.
Most of the time I see fairies in my lounge and maybe it is because there is a lot of light, big windows and a big garden in front. I saw a fairy silver/blue very bright fall in front of me. It was like watching a shooting star or a comet. It didn't happen very fast so I was able to get a very good look. These fairies are tiny. Sometimes, if I don't look at them head on, they linger for a while longer.
There have been days where my lounge is full of them coming and going, appearing and disappearing. I have seen dark fairies too, they are to explain....three pointed star shaped, they come and go really fast. What is the difference between the silver fairies and the dark three pointed ones?
Sometimes they appear near each other. On one occasion they were actually mingled/blended together.
