Dream of

I am walking in a dead world, but in familiar places that I recognize. The clouds are only 200 feet above my head, dark, and moving fast, but there is no wind. I'm walking in a dense, dark grey dust, or dirt, very fine like sand. I am exhausted, but I keep putting one foot in front of another. There is a voice whispering in my ear, telling me it's not so bad as long as I keep moving ahead. So I keep walking, and walking. I am the only living thing in this world, I am alone. The voice in my ear is my mothers, she passed about 2 years ago. When I wake up, I realize I have had this dream almost every night for around 18 months. I am overwhelmed with emotion, I am exhausted, mentally and physically.
