Just because I keep having thoughts and small daydreams about dying and death does NoT mean I’m going to die right Now, right???

No. It doesn’t mean that at all. It means your brain is normal. Humans think about their mortality. It is our nature to do so. You might just have some Obsessive tendencies that is making it worse.

Nope, just means for whatever reason you're having dreams of it ;)

Right. I had them. I'm still alive
