My mom passed away 6 years ago and today I woke up tearing cause I had a dream that me and my family were visiting my mom where she was in the hospital and when I seem her she was happy that she loved us and we huged herm. I'm the oldest by the way I have one sister and two brothers. Anyway one day in my dream we told my mom we will come back that we're going to go get something's all off all sudden when we left the hospital got full of water and my mom passed away cause she drown but in real life that wasn't the way she passed away?? Later in my dream I went to one of my mom close friends and I told her what happen n I started crying in my dream n her friend. Said " don't worry she is looking down on you and god is with her" then I woke up crying. What does it mean??

According to the book "Dreams and dreaming", a dream about your mother indicates that it is a time for nurturing and supporting.
The drowning part? To dream that someone drowns is a sign of stress, and a message from your subconcious to take care and slow down. It signifies that you are felling totally overwhelmed and helpless in the face of too much pressure. Or it could also mean that you have not been openly acknowledging feelings of suffocation. Other people are leaning on you too heavily, and the dream is a message to step back.
You may be aware that closure is needed around an issue that you have been dealing with. Let go, and channel your energy in a different direction.

I hope that helps.
