Is it normal to feel kinda like 'airy'

Sometimes i feel like im completely drained or kinda just like all my insides got replaced with air. Idk a better way to describe it. Its like im usually bored in many things, but especially then when i feel that way. And like for the past couple of days ive been somewhat high on energy so maybe im tired from that? But usually it just happens randomly so idk. Sorry if this doesnt make sense and stuff
