Are numbness in the feet and headaches when reciting Surat Al-Baqarah, and disturbing dreams such as fleeing from an octopus or a black scorpion, symptoms from Satan?

We have no knowledge of the reality of what afflicts you, and you can ask a trustworthy person specialized in ruqyah. Disturbing or evil dreams are from Satan. When seeing something disliked in a dream, one should seek refuge in Allah from its evil and not mention it to anyone, and spit lightly to the left three times. To get rid of them, it is recommended to read the Quran, supplicate, frequently remember Allah, and sleep in a state of purity.
