Surge of energy

So I'm 37 weeks as of today and we got home from trick or treating (ton of walking) and just a long day and I went from super tired to a surge of energy and the urge to clean and work... it's like 3am now lol an dim barely settling into bed. Wondering if this surge is a sign baby will be here sooner rather than later. Like a nesting surge maybe? lol anyone else have this?
