Alzheimer's Disease

The presence of Alzheimer's disease in your dream indicates a fear of aging and loss of ability whether it is mental or physical. This is a general concern for many people, and therefore a common dream to have especially if you're in the late middle age.
In the case that there is someone in your waking life with Alzheimer's disease, this dream holds even greater weight. Take this as a reminder to maintain a healthy mind as well as a healthy body.
