If im seeing spots in my vision like squiggly lines black and brown and my eye really dark does that mean vision loss? i have hydro

Needs evaluation: These spots are a change in the vitreous or even the retina. Make an appointment with your ophthalmologist.

See eye doctor ASAP!: Squiggly lines in the vision with what sounds like a loss of vision (as you describe"dark vision") is worrisome for a hemorrhage inside the eye or a retinal detachment. While the floaters you describe are often associated with normal aging changes of the vitreous gel, sometimes complications like bleeding or a retinal detachment can follow. See your eye doctor immediately!
