You could instead say something like "I don't know."
Unfortunately, a lot of people (especially engineers) default to attempting to discredit people's strange experiences and instead regurgitate some hand-wavy materialistic explanation that is incorrect or at least so incomplete and hand-wavy as to just derail the conversation instead of improving it. I was this guy when I was younger, but I prefer being open-minded nowadays.
Specifically with regard to people's experiences, I tend to treat them with a strong curiosity. You can never really tell on the internet, but in person, I think people are generally quite honest and don't really lie about things that don't benefit them in some way. If you approach things with an open mind, people tend to be more open with their experiences, and it seems like at least 10% of people I know well and possibly many more have had some inexplicable experiences of the variety described by the parent poster (albeit usually over a much shorter period).
