Why is my sleep different during my period?

During my last three menstrual cycles, I had an intense energy shift the night before my period. I weirdly had the energy to randomly stay up until 2 am (usually I’m in bed by 11 pm). During the last cycle in particular, I took note of this seemingly random energy spike & did a little digging on the internet to see if there was any scientific reason as to why this was happening to me.
