Attempted suicide in dream?

Killing in a dream means a sin. Killing your mom or anyone for this matter means you have committed a big sin; then killing yourself means that you want to repent and stop doing that bad thing. In other words, you are thinking of readjusting your life. The hospital shows that you are afraid of sickness I don't know if it is any specific disease. This part could be irrelevant in your dream. But listen to your guts and subconscious mind, if there are mistakes and bad choices you are making and people like your mom telling to stop, it is good to listen. It is for your own good.
