Yes, Felipe. One can use that expression as an equivalent as well, context-wise, of course.
In addition, to the repertoire given, I will offer my two cent´s worth.
To live in (a state of) denial.
...is used for a psychological defense mechanism postulated by Sigmund Freud, in which a person is faced with a fact that is too uncomfortable to accept and rejects it instead, insisting that it is not true despite what may be overwhelming evidence.
The subject may use:
simple denial: deny the reality of the unpleasant fact altogether
minimisation: admit the fact but deny its seriousness (a combination of denial and rationalization)
projection: admit both the fact and seriousness but deny responsibility by blaming somebody or something else.
The concept of denial is particularly important to the study of addiction. The theory of denial was first researched seriously by Anna Freud. She classified denial as a mechanism of the immature mind, because it conflicts with the ability to learn from and cope with reality. Where denial occurs in mature minds, it is most often associated with death, dying and rape.
