Are dreams of the deceased true, and is what the questioner saw in his dream of his deceased mother considered good tidings for him, and is his arguing and shouting at his mother considered an act of disobedience, and is not kissing his father's hand daily considered an act of disobedience?

We hope your dream about your mother and her news to you, signifying her contentment with you, is a good vision. However, we must point out that interpreting dreams is not our specialty. We advise you to seek forgiveness for your mother, give charity on her behalf, and maintain ties of kinship with her relatives. Dismiss from your mind what you mention about your own ill-manners or being the cause of her death, as this is a deception from Satan. Occupy yourself more with studying the Quran, books of Sunnah, and stories of the righteous predecessors, and seek out good company. Kissing the hands of parents is recommended, and kissing their foreheads is even more preferable. Not kissing them is not considered an act of disobedience.
