No, it was an external presence that spoke only to him, with a very clear message delivered to him that day. A message that changed his life. As a rabbi I have been asked many times whether Jews believe in angels. Our Torah study group which meets on Shabbat mornings has wrestled with this question. Especially in studying the book of Genesis, you cannot get around the subject.
Angels are everywhere.
Three angels visit Abraham in the heat of the day, and one announces that Abraham and Sarah will bear a child in their old age. That boy, born out of laughter, will later be bound on top of Mount Moriah. Abraham's grandson, Jacob, encounters angels in a fearful moment of his life. Fleeing his father's house after stealing the blessing of the firstborn, Jacob is alone. He lays down to sleep in an unknown place, and then dreams.
