Feeling high after 4 months of quitting weed?

I quit weed 4 months ago, I don’t know if it’s dissociation or derealization because I’m not disconnected from the world or the people around me but it feels like I’m high but I don’t notice it when I’m inside my house, but every time I go outside at night and specially when I’m driving I start to notice it way more, it feels like I’m high just stuck in my head, but when I come home I don’t notice it a lot, and specially when there’s a lot of light I don’t notice it. when it’s dark I notice it way more, and specially when I’m driving during night time. Can some of you guys tell me what this is, and when does it go away because it’s been constant 24/7. I abused weed and carts for 3 years.
