We all dream, but many of us don't really understand why. What do we know about the purpose of dreams?

Why do some dreams feel so vivid and memorable while others disappear the moment we wake up?

Dr. Christine Marchionni is the Program Director for the St. Luke's Psychiatric Residency Program.

She joins hosts Amie Allanson Dundon and Kevin Crockett  @crockettonair  to discuss what can be explained about our dreams -- and how closely nightmares are linked to stress, anxiety, depression, or trauma.
