Did you wake up in the same place your body was in your "dream" or did you wake up laying in bed like you normally do when you wake up?
My question too, Because if so, that is truly fascinating. One would think that if you were to answer yes, you must have been in such a light stage of sleep that your body was carrying out the motions with your dream, while you dreamt of the book shelf. Kinda scary, really. But cool none the less. I'd deem this a lucid dream, With physical mobility.

OR, Your eyes WERE open, you were perceiving the bookshelf as per usual because your eyes were perceiving reality. However, during this, Your BODY was in sleep mode/dream mode still. You simply thought it was a dream, so just as your body is slowed in FA's, your movement is slowed in reality as well. I wouldn't deem this concept a LD.

Either way, pretty cool experience Laurelindo
