Is it normal to wake up like this?

Is it normal to wake up in a sort of zombieish like state where you are aware of what you are doing but you aren't thinking about anything and just doing it?

Since this sounds a little bit confusing I'll give an example; This morning I woke up from hearing loud bang's outside which turned out to be thunder, but when I woke up I ended up going up stairs *my rooms in the basement* pet my dog, then went outside. I didn't really become aware of what I was doing in till I pet my dog, but I continued to act with out wanting / thinking about doing anything. I didn't start to think and act on my own in till I got out side.

Is waking up like this and doing stuff normal? It's only happened a handful of times to me but lately it's been happening more frequently :S
