In her dreams, she often experienced a sense of unreality that made everything feel strange and distant.
Unreality → It is formed from "un-" (meaning not) and "reality" (from Latin "realitas", meaning the state of things as they actually exist). The word "unreality" means the state of not being real or lacking reality.
Think of 'not' ('un-') being added to 'reality' — this helps you remember that 'unreality' refers to something that is not real.
