Secret Nighttime Rituals

I've been sneaking into my room after everyone else is asleep for over a year now. It started as just curling up with my childhood teddy bear and feeling safe, but it's grown from there. Now I set out little snacks for myself and my imaginary 'protector,' laying out blankets to make a tiny fort under my desk where I can hide. I dress in old pajamas that smell like home and wear my hair down to look younger. It feels silly, childish even, yet comforting too, a way to cope with stress and anxiety when the world outside seems too big. I've never shared this with anyone before and it makes me feel embarrassed and ashamed. Is there something wrong with needing these secret moments? Am I alone in finding comfort in regressing like this?
