I-I found a weird device 
in my locker earlier.
.وجدتُ جهازًا غريبًا في خزانتي قبل قليل
I-Ich habe vorhin ein seltsames
Gerät in meinem Spind gefunden.
Es que hace poco vi
algo raro en mi casillero.
Es que antes vi
un chisme raro en mi taquilla.
J’ai justement vu
une machine bizarre dans mon casier.
