What is the interpretation of my feeling of something pulling me and entering my body and making it heavy during sleep, and the difficulty of reciting adhkar, and the repeated experience of feeling something strongly grasping my body and paralyzing my movement, despite my constant listening to Surat Al-Baqarah?

It is not possible to determine with certainty the cause of what happened to the questioner. It might be a touch from the jinn. Therefore, it is recommended to maintain the regular prayers and the prescribed remembrances (adhkar), such as the morning, evening, and pre-sleep adhkar, for they are a fortress against devils. The Messenger of Allah likened the remembrance of Allah to a fortress that protects the servant from their enemy.
