Hello, i would like to known if i put a Frozen on the location of House of Dreams, blank the text of the location.

No, because the location is immune to the effects of that attachment. (Since attachments are non-plot cards.)

I'm curious as to what prompted this question.

i think unless the location is no attachments, you can attach frozen solid to it. it just wont do anything since it is immune. same way you can attach a frozen solid to a black raven, then give the frozen solid the raven trait in another action window.

Everyone seems to remember, when trying to figure out if immunity applies, that you cannot target the immune character, but they always seem to forget that, targeted or not, immunity lets the character ignore all direct effects. So you point out that Westeros Bleeds doesn't target anything, but still misses against event-immune characters. Then they remember.

Attach Frozen Solid to your opponent's HoD location, so he cannot bounce it with S&D. Standard play…

Why would your opponent be attempting to bounce their own location that is immune to your attachment's effect back into hand?

Exactly, they're far more likely to want to protect it from yours…
