The meaning of unknown is I do not know. The meaning of unknown is not nothing. It is better to say I do not know than to say it is nothing.
Because it is not logical.
For example: Can human dreams connect to the unknown universal in some way?
You can say I do not know, but you cannot say it is impossible, unless you can prove it is really impossible.
This may be the most important psychological complex of modern people.
They dare not to study the unknown. They deny them.
