Something happened today, shortly before we all left the picnic. I can't really explain it, but it was just so... odd.
We were all packing up to get ready to leave as the sun began to set. We were getting ready to bid our farewells for the day, when the ground started to shake. Off in the distance, near Canterlot, a bright white beam shot up into the sky. It pierced the clouds, then created a small shockwave before disappearing. For about two seconds, the sky turned a saturated red, then changed back to it's normal blue self.
As this happened, I felt a strange sensation wash over me. I can't really describe what I felt, but I definitely didn't like it. The hair of my mane seemed to stand straight up, and my eyes opened wide, while my pupils became incredibly small. I felt a sense of fear start to overcome me, before it faded away when the sky returned to it's usual blue tone.
I asked if any of the other ponies had felt it. They did. We all just stood around, puzzled, trying to comprehend the event that had just taken place right in front of our eyes.
Something's definitely out of place here. Nothing like this has happened before, and we're all very uncomfortable with what's happened just now. We all finished saying our goodbyes, and continued home acting like it'd never happened. It may just be something small and harmless, but I'm still worried.
I'm going to Canterlot tomorrow. Maybe Princess Celestia has some answers.
