I just remembered one more story about my childhood that puzzles me

I was about 6 years old and i was waken up in the middle of the night by my mom. She told me to get dressed. She told me to be quick and i remember getting into the car and we were driving. It was storming outside and i remember feeling uneasy and scared and i remember seeing purple looking lightning in the sky. We went to my grandparents house and my grandma was up waiting for me. I got dropped off and my mom disappeared and i got picked up the next morning.

I have no idea what that was about because she wouldn't tell me anything then. I just remember being scared and uneasy for some reason. I wonder if she would remember that night and would tell me now. I mean she's in her 60s she might remember
