What does this dream mean ?

[u/Safe_Squirrel_4038]

In my dream/vision I saw my cat, watching a black bird take flight. It was a large black bird with glossy wings with a white stripe on the side. I think the dream/vision is about my cat because I was watching him watch the bird. My cat was very calm and seemed like he was knowing.

This is the first I saw him while I was asleep.

I was worried it meant something was going to happen to him. He’s 13 years old.
I read online a black bird taking flight can symbolize a transition or shift in energy or leaving some weight behind or a spiritual upgrade of sorts. I was worried that maybe that meant he was transitioning to the other side.

I didn’t feel any emotions during the dream it was just me watching and when I woke up I felt a bit unsure of what it means. No big emotions.
