Just to add confusion, Not all unicorns are either mythical or fictitious
While the claims made by Brexit may eventually prove to be false, they cannot be 'fictitious' if you and others are able to quote them

Not so:
'Twas brillig, and the slithy toves,
Did gyre and gimble in the wabe ...

Of course fictional things can be quoted.

I didn't claim that fictional things can't be quoted. But 'fictional' & 'fictitious' are not interchangeable.
Lewis Carroll's writings are a matter of fact, they can be found in any good library. While their subject matter may be fictional, one can still quote them.
If you tried to attribute something to Lewis Carroll which he didn't write/say then that would be a fictitious quotation.

As Dave The Gnome says:
Different language anyone?
