Burst of energy

So suddently, at 11:42 pm I have a huge burst of energy. Lately I've been having trouble sleeping but tonight I feel wired. I've literally gotten up twice and danced.... Like danced all over in my living room and in the bathroom mirror haha now I want to go do things in my house but hubby is sleeping. I've been having pre labor like pains but no actual labor... Is this a good indicator that labor might start or am I just crazy? Like I have a lingering tiredness like my eyes are tired, but I don't want to sleep at all. Anyone else get this? My dancing made me crampy so I'm laying down now but I want to get up again haha. I'm also SO HUNGRY
