I am not an advanced meditator,i feel the same thing while i am meditating,also i know that it's a normal process in meditation, seems like you are doing right i think.I think you are feeling your real Self,and you are not aware of anything other than your real Self,it's real You i think.In that process,you are pure consciousness-awareness,which is aware of only itself,and it is limitless,so you don't feel that you are limited in a body i think.So you may feel that you are nothing and everything at the same time,you are feeling-aware of your real identity in meditation.
In everyday life,you give attention to your body,objects,cicumstances,problems and you become aware of them...But in meditation,you give attention to your real Self, and thus you start being aware of your real Self.When you don't have any thoughts,your mind stops and you are pure consciousness-awareness which is your real Self.
