Can consciousness exist externally without physical body?


In The Immaterial World this is possible. There might be times you fee so in meditation. Maybe when you enter Infinite Conciousness Absorption but even without this there maybe instances you may fee so.


  What is this state ?


You been born in an Immaterial World.


  How can this be explained in Buddhism?


You have generally have Nama &amp; Rupa. In Immaterial World you just have Nama but not Rupa.


  Sometimes I feel that my consciousness is separate from my body.


This is not possible as I would believe you to be human hence having Nama and Rupa, in which case conciousness cannot exit without a physical body. This is the case in any other plane of existance other than The Immaterial Worlds.
