Well looks like a lot of us are given visions/dreams/warnings.
Always pay attention to these visions/dreams, always, they are signs and messages. For some reason the ones with this "gift" have been given a glimpse into the future for a reason.
The Holy spirit selects chosen ones (as he did his disciples ) to spread the word, to be a messenger or to prepare them for the times about to come.
God chooses those he knows will be faithful and believe, he knows exactly who is going to accept this and who is not.
I am giving visions all the time, and my dreams I remember from 10 years ago. They are symbolic of course but somehow I can figure it out well most of the time anyway. Sometimes its not until after the fact.
I started having precognitive dreams over 20 years ago, however I was not ready to understand them, then the pattern became repetitive, it started becoming more clear to me.
I had this one dream where I was looking out the window and watching firefighters, and police rushing on the streets, I seen a big building in my dream fall and people with bandages and cuts and some dead. I remember this plain as day. I also remember my face, I looked so sad and so helpless.
Well one week later the Haiti earthquake hit and then I knew what my dream meant.
I do not believe in "dream books" that is a bunch of hog wash. It all depends on what and how your dreams are given to you and what surrounds your life.
Every one of us are given messages in different ways that we are able to understand. Its like your children, if you have more than one, each child will be spoken to entire differently depending on their personality;.
I would like to be able to find missing children and feel if I ask for the gift I can receive, however I don't believe in using what gifts given to us for our own personal gain.
