Sometimes people combine in the words "illusion" as well as "allusion."
An allusion is usually an implied plus indirect reference or even a suggestion. Allusion is a program typically used in works of fiction to see about anything at all with out specifically speaking about the idea. I used this specific machine in the Tip Topic today, obliquely creating a term play below using the lyrics within your Styx melody. But now I am not alluding to barefoot jogging, because I referred to it quickly. As a result, use "refer" to have one on one mentions, in addition "allude" to get indirect states.
Illusion is usually tricking, deceiving, and also fooling someone into thinking something can be real when not. Masters of magic often score well in the skill of impression, presenting the particular false impression of which one thing evaporated, when it was really your own focus which was redirected in other places.
