Dreams involving changes in appearance, such as dyeing your hair, often symbolize a desire for transformation or self-expression. The holographic style may suggest that you are exploring different facets of your identity or how you wish to be perceived by others.

However, being sent to a psychiatric hospital can indicate feelings of anxiety, fear, or a sense of losing control over your life. It might reflect concerns about your mental well-being or a need for a break from stressors in your waking life. This juxtaposition of self-expression and confinement could signify inner conflicts or pressures you are experiencing.

Consider reflecting on any recent changes or challenges in your life that might be contributing to these feelings. It may be helpful to explore ways to express yourself more freely and address any underlying anxieties. Journaling or talking to someone you trust can also provide clarity and support.
