Something weird happened

So about a month ago i harvested one of my plants, but left it in the soil in the garage to dispose of at a later date.. Just remembered it today and it has new growth, my garage is pitch black and it obviously hasnt been watered how is this possible

It’s a sign to reveg and clone it. It wants to run again

Yup sure is if it survived like that she wants life. She probably sucked up what water was left in the soil
