Last night I had a dream in which I saw my deceased grandfather. He held my hands and spoke a few words into my mouth. It was so vivid that I was sure it was real. Although, well, it was still a dream. Dreams are a representation of what our mind sees when we have no control over it. They can be caused by many different factors. But this dream was so vivid that I felt a tension as he held my hand. I wonder what the Kabbalah says about dreams? Is dreaming a way to communicate with those left behind?
