INTRODUCTION
An illusion is an important part of perception which helps us to understand the process of perception to understand what is illusion exactly and what role it played in our perception. An illusion is that movement when we observe any stimulus and make a wrong prediction about that stimulus because our sense doesn't observe it properly and gave a wrong signal to our mind about that stimulus that we predict it wrong. For example, if you are walking on the street and suddenly if felt that you have sen someone knows to you but suddenly you realized that you observed wrong that one just has some resemblance to our known one that is known to you.
Illusion helps us in perception by giving us information that is similar to the present stimulus and collect information related or resembled it and complete the perception process, that is why we can say illusion is a part of perception only, which we almost experience every day or very frequently in our daily bases and that help our brain to make related information visually.
