Just curious, does anyone have trouble sleeping the night they do deadlifts?

I work out after work usually around 7:45 pm and I've noticed each and everytime I hit Deadlifts/Back HARD I have trouble sleeping that night.

I feel no pain or discomfort just wide awake. I'm assuming it's because it's hitting my CNS pretty hard but of course that's just an assumption. I'm just curious as to any other people have experienced this.
