All perfect praise be to Allaah, the Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His Slave and Messenger.
These symptoms do not necessarily mean that you are affected with jinn or the like. It is better for a Muslim not to hasten to such judgment in order to avoid involving himself in illusions.
You should consult specialist doctors as there might be a physical disease. If there is no disease, then you may be affected with an evil eye, or possessed by jinn and the like. So, you should be keen on performing Ruqyah which is beneficial – Allaah willing – for protection against physical and psychological diseases. In any case, you should continue to perform Ruqyah. For more benefit, please refer to Fataawa 5241, 25030 and 9800.
As regards your dreams, they might not have any relation with being possessed by jinn, as this may be caused by the devils that are playing with the human being or are just one’s inner thoughts. It is confirmed that the Prophet said: ''There are three types of dreams: a good dream which is glad tidings from Allaah, a dream of sadness from the devil and a reflection of one's thoughts (i.e. experiences one has during wakefulness); so if any one of you sees a dream which he does not like, he should get up and offer prayer and he should not relate it to the people.” [Muslim]
Therefore, you should not take these dreams into consideration or be concerned about them, or abandon the Ruqyah because of something that you saw in them.
Allaah Knows best.
