Dua when feeling alarmed/ fear/ anxiety & unrest in sleep:

اَعوذُ بِكلمات الله التامّاتِ من غضبه و عِقابهِ و شَر عِبادِه و من همزات الشيطان و اَن يَحضرون

A’aotho Bikalimaati Allah Al Taamaati Min Ghathabhi Wa Eiqabh Wa Shar Eibadih Wa Min Hamazaati Al Shaytaani Wa An Yahdoroon

“I seek refuge in the Perfect Words of Allah from His anger and His punishment, from the evil of His slaves and from the suggestion of devils and from their presence”.
