They would both be nice to have. I want the ability to grow bigger! I wanted growing powers since a little boy so I could become a giant anytime I like. I would love to see everything appear smaller due to me growing bigger and bigger and bigger!!!
You probably already have super powers but just aren't working to develop them! Try a bit of meditation and see if that can help you break through to the 'super-new-you."
Both. Flying just above the ground has been a popular dreamland superpower for me since I was a kid. I take longer and longer steps and I just start skirting a few feet above the ground without touching the ground. I love to go higher but I can't seem to influence what happens in my dreams.
"The Invisible Man" was a popular movie. I swore as a kid that if I had that ability I'd use it for good only. Well, mostly :)
