There is a growing trend in the world today to make people doubt themselves, especially those who may have had a spiritual experience. The doubters say, "it was a state of hypnosis, you imagined it, that's what you believed you saw, you were mistaken, it was probably an animal... or... you need to see a shrink." The list goes on and on...
I believe that when one sees anything that seems out of the ordinary, that we have to search every possible explanation before we can label it as supernatural... But then on the other hand, there are those experiences that are so clear and unmistakable that they leave no room for any doubt about what was seen. Yet the narrow minded person will try to make you doubt your own eyes... even your sanity. In some cases, they will even try to shame or embarrass you into admitting that you were probably just hallucinating.
Matthew 7:6 says, " Give not that which is holy unto the dogs, neither cast ye your pearls before swine, lest they trample them under their feet, and turn again and rend you." .. In other words, be careful who you share your spiritual beliefs and experiences with because some individuals will trample over them and then turn on you with harsh or hurtful words.
Of course, we should all be sensible about our experiences. As said above, explore every avenue and make sure that there is not any other cause for what you experienced. If you're the kind of person who thinks every little happening is otherworldly and saying you're having a supernatural experience every other day, then yeah, folks will probably be very suspicious of your claims. But when it comes to those legitimate occurrences that come out of the blue and leaves you mystified and blessed for having experienced it... don't let anyone take it from you with clever words or belittling attitudes!
