I'm a bit of unsure about the following sentence - 「知らない人の声が頭の中に聞こえ、そんな異常事態をなんとなく受け入れてしまっている自分がいる。」. There are lots of strange things happening to MC and one of them is hearing voices inside her head. Is it correct to think that そんな異常事態 is about strange things other than hearing voices?
Maybe my question is unclear, that is why I try to write a translation of this sentence: "And there is me, who hearing the voices of unknown people, somehow or other accepting this abnormal situation." is this translation looks fine or not?

知らない人の声が頭の中に聞こえ、そんな異常事態をなんとなく受け入れてしまっている自分がいる。
