Istikhara, OCD And Dreams
If the intellect is giving a clear verdict then one should not bother about dreams. If the matter is doubtful, then one should make a decision after thinking it thoroughly and then go for it. Allah will definitely open ways for the person in hundred different ways which may not necessarly be a dream all the time. And if by any chance, any dream is shown then those dreams are crystal clear to the person without any doubt.
