Last night while asleep I met my friend and colleague Peter, we studied together for three years. Peter sadly died last year suddenly from heart condition.
My question is if my conscious mind knows that Peter is dead does my subconscious mind think that Peter is still alive ?


Seeing a dead person in your dreams, means you are hoping to see them again, or you are going through the grieving process, or going through any number of possibilities for a better outcome than what actually happened.
Some dreams are your subconscious mind trying to have you understand some things. A dream about a dead person would be wishful thinking, happiness, memories, etc.
