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 is His slave and Messenger. We ask Allaah to exalt his mention as well as that of his family and all his companions.
We have already issued Fatwa 90123 about a man who, when suddenly awakened, he may unintentionally harm others.
We explained in this Fatwa that he is not responsible for what he is doing as long as he is doing so while sleeping and that he should consult doctors and should recite Quran and the legislated mention of Allaah when going to sleep while in a state of ablution.
Anyway, the things which you mentioned, that you walk, talk, yell, and scream in your sleep, and worry about the members of your family, and call your father and mother to make sure they are O.K., then all this might be due to a physical or psychological problem, and it may also only be nightmares caused by the devil. However, it is most unlikely that this is due to being single. On the other hand, getting married is better as it is confirmed that the Prophet said: "O, young people! Whoever can marry should marry, as it helps one lower their gaze, and protects one’s private parts (from illegal sexual intercourse)…" [Al-Bukhari and Muslim]
Finally, it should be mentioned that it is good to consult a psychologist and you should continuously recite the legislated mention of Allaah and supplicate Him to repel these things from you.
Allaah Knows best.
