Strange experience after visiting Buddhist place
i visited a buddhist place in a country i had never been to before in a family tour group. just for some background, the location was very vast and had a long and ancient history. it also had sarira so i believe that means it was a very important buddhist location.
there was a running water fountain filled with blessed water (?), and i was told to splash a little on my head for good luck by the tour guides, which i did. that night, however, i woke up all sweaty with a throbbing migraine and chest pains. i also experienced nightmares and sleep paralysis, and when i woke up, i felt unusually heavy and as though the lights were extremely bright. everything also felt like one big dream.
i am usually a regular sleeper, rarely have dreams, and generally do not get headaches. i also almost never wake up during the night, not even to use the bathroom, so this experience really scared me.
i was wondering if anyone knowledgeable about buddhism could kindly explain how this might be understood from a buddhist perspective. i am not necessarily assuming that something big happened, but because the experience was so unusual for me, i would really appreciate hearing how a buddhist might interpret it.
