A state of being confused about where you are, what time it is, or who you are.
After waking up from the surgery, she felt a sense of disorientation and couldn't remember where she was.
Disorientation → It is formed from "dis-" (meaning apart or away) and "orientare" (meaning to set in a particular direction). The word describes the state of being set away from one's direction or sense of position.
Think of being 'set apart' ('dis-') from your 'direction' ('orientare') — that's why disorientation means losing your sense of direction.
