i have spoken to people who after i asked them told me to have witnessed something which could have possibly not be explained with any other convention then something to dcall it supernatural or alien. it's a fun question to ask someone who you've met or know for a while and see how surprisingly many people have stories or know someone who has a story. To me this was incredible because ordinary people don't have to make up things like this when they tell it after you've plain asked in confidentiality. That was a cool revelation for me until I've had my own strange experiences. And at some point things started to happen (also when there were other people) so often that I think these things are normal for people, that everyone has witnessed something they can't explain. And choose not to talk about on a daily basis because people can't really relate to things they can't understand.
That said... it's only when you start to open your eyes for these things that you realize it's impossible to deny that there is more to this life. then what we can see.
