The most noticeable thing about a giraffe is its height, which enables it to see things from a higher perspective.
So if you dream about a giraffe, it can mean that you are looking at things from a perspective that is too mundane, and you need to see things from an intellectual or spiritual viewpoint.
A dream that you are riding a giraffe can mean that you are seeing things from a higher perspective for the first time.
If you dream about a sleeping giraffe, it can be a sign that you are not paying attention to the things that are around you.
A giraffe has difficulty bending down. If you see a giraffe bending down in your dream, for example, to drink, it can mean that you are having difficulty accepting a compromise about something.
When a giraffe bends down, it is vulnerable to predators because it cannot run away easily, so this dream can mean that you are afraid that if you give up control of something, you will be vulnerable.
Giraffes have very flexible necks, so a giraffe in a dream can be a sign that you need to be more flexible.
