You have no idea.
You can't even imagine.
More than you can imagine.
Parce qu'on est plus semblables que tu n'imagines.
Because we're more alike than you think.

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)
