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.
First of all, we thank and praise Allaah Who guided you to Islam and we ask Him to make you firm and steadfast on His Religion until the Day you meet Him.
You should know that nothing happens in this world except with the Predestination and Will of Allaah, and that the extraordinary occurrences are one of three kinds: either a miracle for a Prophet, or a Karaamah (extraordinary act) for a Waliyy (an ally of Allaah), or a gradual dragging from Allaah and a seduction by the devil. We have already issued the ruling about it in Fataawa 101347 and 86489.
Therefore, you should be careful for what happens to you to be a gradual dragging from Allaah or a plot of the devil in order to spoil your religion.
As regards feeling things before they happen, like knowing that someone had died before the news of his death spread, or informing your friend that the police had taken her husband, then this is a restricted Ghaib (unseen) that some creatures may know and some may not know. For more benefit, refer to Fatwa 85037.
Concerning what you mentioned about the jinn, we advise you to seek the help of Allaah to repel their harm and also to recite the Quran at home especially Surah Al-Baqarah (the Cow, Quran 2). Moreover, you should be keen on performing good deeds and avoid committing sins, and you should endeavour to protect yourself and your family against Satan and his soldiers who cannot harm you except with something which Allaah predestined for you. Allaah Says (what means): {But (they) do not harm anyone through it except by permission of Allaah.}[Quran 2:102] Furthermore, the Prophet said: ''Know that if the whole world gathered together to benefit you, they could not do so except by that which Allaah has destined for you; and if they gathered together to harm you, they could not do so except by that which Allaah has destined for you.” [At-Tirmithi]
With regard to your dreams about your second pregnancy, seeing Jibreel (Gabriel) and the Prophet in a dream, then this is a good dream, Allaah willing. Abu Hurayrah narrated that he heard the Prophet saying: ''There is nothing left from the prophecy except the things that give glad tidings. The companions asked: “What are they?” He said: ''A good dream.” [Al-Bukhari]
Finally, there are some etiquettes in Islam about whoever sees a good or a bad dream. Abu Qataadah narrated that the Prophet said: ''The good dream is from Allaah. So, if any of you sees what he likes in a dream, he should not tell it to anyone except to whom he loves, and if he sees in a dream what he fears he should spit on his left-hand side three times and seek refuge with Allaah from its viciousness and from the evil of Satan, but he should not inform anyone about it at all, and in this case, it will not cause him any harm.” [Al-Bukhari and Muslim]
Allaah Knows best.
