Buddhist view on out of body experience (OBE) Wikipedia defines this as,


  An out-of-body experience (OBE or sometimes OOBE) is an experience
  that typically involves a sensation of floating outside one's body
  and, in some cases, perceiving one's physical body from a place
  outside one's body.


There are numerous studies on people having this type of experience, and I remember Ven. Yuttadhammo once said he also experienced this when he was young.

I think interpretations like astral body projection do not quite adhere with Buddhism.
Are there possible explanations on this from the Buddhist perspective with regards to Five Aggregates?
Why it does not adhere to Buddhism? It does! In all the cases of astral body projection, they were able to see things. What is seeing? Seeing is the union of the light, the eye and the eye consciousness. They had thoughts about what they were seeing and they were aware of what they were seeing. In other words Rupa, Vedana, Sanna, Sankhara, Vinnana. Which means both Nama and Rupa were present. Astral projection does not mean that the mind wanders out without a body. There is a subtle body that goes with the mind. One can't have sensations, if there are no sense doors. Nama cannot be without Rupa except in Arupa realms. That's why beings in the Arupa realms can't see, hear, taste, smell, feel anything.
