My whole family thinks that ghosts exist.

[ROBINDESBOIS]

My whole family thinks that ghosts exist.
if we want to make an impersonal passive sentence out of this sentence, how would we do it?
Just like this:

My whole family is thought to believe in ghosts.
It is thought in my family that ghosts exist.
Ghosts are thought to exist

I don´t think this is the best example of a sentence to be paraphrased.

Ghosts are thought to exist in my family.

The belief in the existence of ghosts is a credence shared among all the members of my family.

That sentence is OK, but you should know that it is ambiguous.
It is believed in my family that ghosts exists may also mean that others think that there are ghosts in your family.

Wouldn't it be simpler "my whole family believes in ghosts"?

[poli]

Those are words truly spoken, Angela. It's been said that the passive is more widely used in English than it in Spanish, but direct and simply spoken English may be heard as well

I disagree.
The prepositional phrase 'in my family' definitely ties to 'it is believed'. It is the family who believes it. What does 'it' refer to? The relative clause 'that ghosts exist'. It is the family who believes that ghosts exist. No one else was mentioned. No one else can be inferred.

Substitute it is believed with they say. It is believed, they say, it is said are interchangeable. I agree that the sentence favors that the family believes in ghosts simply by the placement of the word that in the sentence, but depending on context the other meaning may prevail.
