Observing strict purda with all non-mahrams

Q: Please interpret this dream which I saw a few days ago. I saw that me and my brother are going somewhere and we are at the railway station and we are without tickets and I am trying to hide this thing from few polices, but my brother can't say anything about ticket and then I saw that my brother was beaten badly and blood comes out from his body very badly by police at railway station, and he was crying.

Leaning and eating

Q: I heard an Aalim say that the Kitaabs of hanafi fiqh state that there is no problem with eating while leaning.

1.What does this mean?

2. The Hadith that mentions we must not lean and eat. What type of leaning does it refer to?

Protection from jinn

Q: My question is that one of my friends gave me two copies of letters of Holy Prophet (Sallallahu Alayhi Wasallam) to the jinnaat for protection purposes because once a tragedy happened to me. One copy is translated and the other is not. One's Arabic words are different from the other. Similarly there are some Arabic duas which we learnt but the same are quite different or some extent different from what we read elsewhere. Is it permissible to recite these duas?
