Assalamualaikum,im having severe emotional breakdown.im failing at my academics n my most beloved sisters have gone to abroad.i feel so lost so terrified i pray tahajjud every night n cry for seeking his guidance.today after praying Zuhur salat i was just laying in my bed after a while i saw something blue n white thing im not sure maybe there was written something in arabic it was not so vivid.and i felt like my body is going upwards,like its almost floating.i cannot explain what that was.but then my phone rings and i back to normal.
Can anyone explain please what was that?
