Here are some words that might be what you're looking for:
* Introspective: This is the common word for someone who looks inward at their own thoughts and feelings.
* Perspective: This refers to a way of seeing or thinking about something, a point of view.
* Interspective (made-up word): If you meant a word that combines "inter" (meaning "between") and "spective" (related to perspective), it might be a new term you're trying to coin.
Please clarify what you meant by "interspective."
