I was wondering that too, but as far as the question goes. If you leave soda out, the carbonation dissipates as do the bubbles.
If you leave water out, even a few hours the flavor can be effected by the air, things in the air, the light source etc, so I would say a change in the water from just being left out is normal.
Not sure about having bubbles in your normal water, unless you have a plumbing issue, but anything left out and exposed to the air that normally has bubbles, eventually they dissipate. I’ve seen water have air in it, when there was a hole in the line and things like that, but it usually sounds funny coming out of the faucet too.
