Having Strange feelings after reading Atharva-Veda.

May 2018
so i wanted to study some parts of Atharva veda so i started reading it. mostly Satrunashak/Eenemy destroyer mantras where we pray to gods to destroy our enemies and those evil things who want to harm us.
within 15 minutes of reading those mantra i suddenly started feeling heavy headed like i am having head ache but with different kind, like feeling that you are carrying some king of weight over your head and feeling like i need to puke.

what should i do ?
