In My Head Lyrics

Cover art for In My Head lyrics by Asobi Seksu

I have NO idea what she says in the end... if you can offer any suggestions please let me know.

that being said, this is my favorite song on the album. and at this point in my life I can relate. with my insomnia it's been hard to comprehend time passing. sometimes days feel like weeks and sometimes days feel like hours.

She is speaking Japanese at the end of the song. The lyrics I hear are samishisa hitotsu, hitotsu

And then the "in my head"s at the very end.

I think that in this context "samishisa hitotsu" could mean "only loneliness." I'm not really an expert on Japanese, though. If anyone sees this later and wants to make a correction, go ahead.
