When someone experiences a dead mother complex, it means they have a lot of difficult feelings about their mom passing away. They may feel very sad and miss their mom a lot. They may also feel angry that their mom left them, and they might even blame themselves for it. These feelings can be very strong and make it hard for the person to feel happy or close to other people. It's important for people with a dead mother complex to talk to someone they trust, like a therapist, so they can work through their emotions and start to feel better.
