Crazy baby movement

You know that weird state between awake and asleep when you have a strange dream or something that makes your entire body do this weird twitch jump thing?! Well last night I laid down to go to sleep and my little miss was moving all over the place. Then, wham-o! She moved (I imagine something like from being in a tucked up ball position into full out stretched out) and she managed to make my entire body move, twitch, and jump like that. This is my fourth baby and I definitely do NOT remember having this happen with any of my other babies.
