Most of the time our dreams are what I call "soul leaks." They say something about our fears and anxieties.
But occasionally our dreams are spiritual messages that come from outside us.
The other night, I wrestled with the memory of something I did wrong a long time ago. I didn't sleep well. My dreams disturbed me. One time I even got up in an attempt to wash it out. But when I went back to bed, it stayed with me.
I finally got up and waited until a decent hour to call the person I had offended years ago. I apologized and asked for forgiveness. They gave it.
The rest of the day I felt great. My dreams had become the means by which the Holy One had helped me to clean up my life.
