more wight, more fat..but dont feel fat?!

Has anybody felt like me? I apparently gained 3 pounds the last week. I havent eaten more, did not do as much excercise as I do, but somehow feel light...even after looking at my weight scale with more pounds and more bod fat...My clothes fit better...
Am I crazy ? or is it normal to actually feel good after gaining those pounds I didnt like? i dont see whether they are really there or in the internal organs?
:ohwell:
