Awkward Dreams

Usually, in dreams a person sees such occurrences, which the person does not think of let alone see these happenings, while awake.  These dreams make the person feel awkward and abnormal.  Please can you state a method to prevent such happenings?

When intending to sleep recite Surah Falaq, Surah Naas and Auyatul Kursi, each one once. Thereafter blow on chest and face. If it does not ward off then read Ya Shadeed three times and blow all over the body. Also recite the following dua at the time of sleep:

“O’ Allah, I have put my side reciting your name, and I will rise my side with permission and guard me over my sleep as you guard your pious servants. I seek your refuge from the dangers of Shaytan and from his attending to me.”
