I have been struggling in making a decision so I got out my crystals for insight and divination and as I finished I asked to be given a sign. That night I went to bed and I had a dream were my question was answered. The morning I woke up the dream seemed so strange as if I was truely given a sign. Have any of you been given a sign and do you believe in it?

Yes I do believe in signs. There are always signs around us but most of us fail to see them because we have been programmed not to see them as we grow older.

My mother was having alot of problems with her health and I prayed that night for my mother and I was extremely worried about her. My grandmother (who has passed) came to me in a dream and said everything is going to be alright. The next mornign the doctor called with the results of her test and everything came out positive.

Yes, I have to agree with Sophe that it's the interpretation of the signs or coincidences--as the case may be--that is the gray area.
I have had several instances in which a series of coincidences seemed to be "saying something" to me. But I wasn't clear which way to go on the issue suggested, and the direction of the two choices I seemed to have--that is, the direction that I chose, was the wrong one.
Other times, I can definitely say that one clear choice I made, the choice to look for coincidences, has been very productive for me.

It has caused me to prove that, the more I look for coincidences, the more coincidences I find--that this increases incrementally, far more than mere chance would provide. Some Source is speaking to me, insofar as the recurrence of these coincidences.

I've always been fascinated by the phenomenon of coincidence, anyway. It has many ramifications.
I don't know how well it translates insofar as the issue of signs, and may be a separate thing. But I thought this might be relevant to this series of posts. My own instance, simply seems to be Someone trying to show me that there is more, another level, to events. It has been a source of comfort--like ADCs--but whenever I've tried to see a message that would provide some directional guidance, I've found myself on thin ice and have made wrong choices at times. But this may be, in part, due to my--I can see this in my past behavior on reflection--my tendency to veer back and forth from listening to my right-brain input, to going back and trying to be a left-brainer, coming up with solutions to "perceived" (to a right-brainer, this is actually "imaged") problems ahead of time.
The latter tends to produce negative affirmations, from the standpoint of the right-brain. It works if you are staying only in the left-brain, but when you're trying to use the right-brain, it's counter-productive. It's like--contradictory, in a sense. On the one hand, you're right-brain-ed-ly picturing a positive outcome. On the other, you're "anticipating" something bad happening, or trying to "learn from past mistakes" and thereby imaging negative things and/or making statements about these negative events and images--which, again, has a negative affirmation effect on the right-brain's manifestations.
This is what I've learned about my own behavior. I guess the question is, how much of this involves internal intuitive faculties, and how much was a Larger force around me, taking actions. Apparently there's an interplay between the two though I don't know the specifics.
So, where this takes me, personally, is to try to rein in my own tendency to slip into left-brain behaviors, since I'm a right-brain. We are so inclined to take the "practical" (left-brained) approach of "anticipating problems" and "learning from past mistakes." These classic phrases, I now can see, are working behaviors for LEFT brain people. NOT for Right-brained ones, though. If we're going to use right-brained, intuitive faculties, we have to be consistent. The hope is, since I'm so deeply into this slipping back and forth, that a certain amount of interaction and interplay between left and right is tolerable. Some would probably argue this is just "good balance" and a desirable thing. But I suspect it is something that should actually only be done in very limited amounts, for right-brains.
So--coincidences, synchronicities, and interpreting those, involves perceiving signs, in a sense. These could act as guidance. I've had guidance, and I've had visions that provided evidence of angels, metaphysical/spiritual realities, and life after death.
It's just a simultaneous feeling of hope--that we can hone these intuitive facilities--and despair or fear--that we can't keep from veering back into the left brain, mimicking our left-brained brothers and sisters.
Best,

Yes, not only would you have to believe in signs but you'd have to be able to pick up on them.  It's hard to mix a sign with a coincidence.

I don't really believe in signs.. maybe people are trying to see signs to explain some things that they don't understand or can't.
