Actually dreaming in black and white is normal. Dreaming in color often uses too much of the brains functions and usually is a sign of either a mental illness of some sort or a possible injury to a specific area of the brain. So if you dream in color you should probably get a physical and be sure to tell the doctor that you dream in color, that way he will know that something is wrong and he or she can conduct the necesary tests to find out the problem. Sounds like a lot of you so far have some problems.
