Imagination or Illusion?
Imagination is the image making power of the mind and the ability to create those thoughts.
Illusion is something that seems to be something that is not.
The one thing I think both have is MAGIC. The power of my imagination can bring me wonderful and some not so wonderful things - magic. Illusions can be my misdirected focus that can seem magical at times - magic.
Magic almost appears in the word imagine, just need to add the C from Carolyn and - magic. I make the 'magic' real or perceived, which really is the same thing.
