Man versus reality

What is real and what is imagination? I feel like there is always a constant disconnect between what I wish and what is because reality is often a very random chain of events, but there is a degree of attachment to what is real and what isn’t. This creates a sense of a shared view of a reality mostly made up of what we see and what we feel. This is actually a limit, I say so because there is a wider range of colors to see and experience, but we can only function within a small spectrum of red to violet. This asks the questions why can’t we see more and what is more?
