I was pondering about my labours last night (long night with DD2!) and about how, both times, in the latter stages (ready to push) I had this sudden urge to escape. Both times I was induced and hooked up to a monitor so clearly I wasn't going anywhere, but during my most recent labour I remember saying to DH, "I need to go, leave, right now!" and It was only when I said it that I remembered having yelled said something similar the first time round.
I'm guessing it's a primal thing that's a hangover to when we were all living in caves, having to escape predators etc? But I was still just curious to know if anyone else had experienced the same thing!
