here is Vriska talking to the doctor

she tells him she has been having nightmares about Atsuma
the dreams start off happy and friendly but

they then turn into scary and horrible

the doctor tells her she must forget about Atsuma it would be the only why she will recover

but she doesn't want to

she blames herself that what happened to him
and she will never forgive herself for it

(also this is my version of Vriska)
