I've heard some experiences of some friends in which they explained that they started searching an object to then realize that they were holding it. For example, today, a friend of mine told me that he didn't find his phone, so he started searching it and then he realized that it was in his left hand. I'm sure I've also experienced this more than one time.
Is there a formal name for this specific phenomenom? If that's not the case, what would be the closest concept that tries to explain this?
