When my grandfather died, (Aside from bawling my eyes out.) I decided to ride my bike to let go of the sadness. It was Pure. Clear. Dark. Sky. And this flash of odd light flashes in the sky, no-one saw it but me. Is this something that God did? Or a simple lightning storm. Powerlines? The same thing happened to me when my grandmother died (both on my mother's side.) Odd, right? /Explain?
