When during meditation we forget where we are

As far as I understand, awareness is an important concept in buddhism, and an asset to develop through meditation. During meditation (following vipassana as taught by Goenka), it has happened to me that I forget **where I am** at that moment. When this question/feeling arises, the answer comes little by little being really general at the beginning, and gradually refining to a more detailed description of where I am, like: *you are in this country, you came to this place, you are in a retreat, your are sitting in this meditation hall, etc.* My questions are: - Is this feeling expected at any meditation stage ? - Is this experience maybe pointing out a mistake in the practice ? Answers with references are strongly appreciated.
