To dream of an invasion represents feelings of being threatened by a takeover. Fearing a permanent loss of control or leadership. Feeling ousted or “punked off.” Alternative views or ideas that may diminish you. Feeling that your turf is under threat. Feeling overwhelmed by people you don’t want to be around. Feeling a lack of privacy.
Example: A young man dreamed of his home being invaded. In waking life he was that people who were brought into his home to social by his sister were violating his personal space.
