Dont know if you guppies are interested in this as much as myself, but have a read anyhow.
First Hadith:
“A vision is from Almighty Allah (it’s a form of divine inspiration) whereas a dream is from Satan. When any one of you have a bad dream, let him/her spit out (without saliva) to the left side and recite the two ‘Protective Surahs’ (An-Nas and Al-Falaq) and the dream will not harm him/her, Allah willing.”
Second Hadith:
“At the approach of the Hour, the Muslim will have a true vision, and honesty will help him to have the clearest and truest vision. Moreover, seeing a true vision is the 45th degree of prophethood. Vision is of three kinds: the good one with glad tidings from Allah; the bad dream, which is from Satan to invade hearts with sadness; the third one is the effect of an aforethought matter. So if any one of you sees something sad in a vision, he should offer two rak`ats in prayer and never reveal it to anyone.”
Third Hadith: The Prophet said that if anyone sees him in his vision, he has truly seen him, for Satan can never disguise himself in the honorable form of the Prophet (peace and blessings be upon him).
Narrated Abu Salama:
I used to see a dream which would make me sick till I heard Abu Qatada saying, "I too used to see a dream which would make me sick till I heard the Prophet saying, "A good dream is from Allah, so if anyone of you sees a dream which pleases him, he should not tell anybody about it except to the one whom he loves, and if he sees a dream which he dislikes, then he should seek refuge with Allah from its evil and from the evil of Satan, and spit three times (on his left) and should not tell anybody about it, lest it might harm him. "
(Narrated by Al-Bukhari)
^ no they aren't... although the translations might make it seem that way... the true/good visions mentioned there refer to the good dreams from Allah...
as for visions/dreams in the Qur'an... there are four in the story of Prophet Yusuf (12:4-5, 36, 43-49); also Prophet Muhammad seeing the enemy forces in a dream (8:43); Prophet Abraham sacrificing his son (37:102); Prophet Muhammad's entry into Makkah (48:27)... there may be others
... prior to receiving the first revelation from God, Prophet Muhammad went through a period of true dreams - whatever he dreamt at night during sleep would come true during the day (Sahih al Bukhari 9:111)... this lasted for a period of six months according to some reports and is explained to be a form of training by some commentators in advance of the revelation beginning proper... and then the Angel Gabriel visited him...
the prophet (Allah bless him and him peace) said that if one has a bad dream you shouldnt talk about it or mention it to anyone.
these are not the exact words but it is the jist of the hadith which i read, as for not talking about good dreams never heard of that, if your dreams are good they are mubarak abd blessed dreams so there would be no harm in talking about them.
