Am I crazy??

I'm 38 weeks pregnant and I swear I can see my baby practicing breathing through my belly. I'm 100000% positive it's not hiccups or my pulse. Its quick short breaths the same exact speed as what I saw on my biophysical ultrasound last night. Idk what else it could be. It's not consistent. Itll go for like 20 seconds then stop for a little while and start again for a little bit. No pattern. I swear it's my baby practicing breaths. Anyone else experiance this? It's so neat lol
