you can't imagine
Parce qu'on est plus semblables que tu n'imagines.
Because we're more alike than you think.
— Ghost in the Shell (1995)
More than you can imagine.
You have no idea.
You can't even imagine.
Tu n'imagines pas ce qu'il en a souffert et ça continue.
You can't imagine how much he has suffered because of it, and it’s still going on.
— Le Seigneur des anneaux : Les Deux Tours (2002)
Tu n'imagines pas ce qu'il m'a fallu inventer.
You can't imagine what I had to come up with.
— Cinema Paradiso (1988)
