Have you ever seen a fairy? (the mythological type)?

18 yrs ago I went on a school trip to paint in the countryside and saw a small elf type creature fly past me in an egg - it was the size of a fingernail - my friend saw it too - we each drew what we had seen without describing it - we just said 'hey, did u see that? draw what u saw' - witnesses were present and our images were the same.
