As-salamu `alaykum. During the night, when I am sleeping, I get this strange sensation that almost paralyses my whole body and prevents me waking up. The worst thing is that during that time, I think something is having sexual intercourse with me. I would like to ask if it is Satan causing this to happen, and if so, how can I fight against this bad thing?
This problem is called "Sleep Paralysis" and has some scientific causes and treatments. You can read about them here. For example, there's said that:
Up to as many as four out of every 10 people may have sleep paralysis. This common condition is often first noticed in the teen years. But men and women of any age can have it. Sleep paralysis may run in families. Other factors that may be linked to sleep paralysis include:
- Lack of sleep
- Sleep schedule that changes
- Mental conditions such as stress or bipolar disorder
- Sleeping on the back
- Other sleep problems such as narcolepsy or nighttime leg cramps
- Use of certain medications
- Substance abuse
Doubtlessly, reciting Quran before sleep (especially Ayat al Kursi) and getting to sleep with the remembrance of Allah will complement these treatments.
This is not "Sleep Paralysis" as the previous answer has been stated. It is clearly the problem of a Jinn.
The most important thing to get rid of the Jinn is start getting closer to your Creator Allah (s) through His obedience and getting rid of sins.
Always stay in wudhu. And before Sleeping recite Surah Ikhlas, Falaq & Nas three times, Ayatal-Kursi and blow it on your hands and rub it on your whole body.
You may need to visit a rakhi to solve your problem. And remember a Rakhi will never ask your mother's name and if someone does then he is a Magician.
