Dreaming that grandpa will be cremated: Similarly, dreaming of cremation generally represents purification and is related to change. If my grandpa in my dream has passed away, it represents the coming of change, because the death of si usually symbolizes the end, overcoming and forgetting, that is, the end of an old stage and the beginning of a new stage.
Dreaming that grandpa was awakened: it means that it is still not over, for example, a problem is still unresolved and still hovering in the old stage.
Dreaming that grandpa has no eyes: eyes are the windows of the soul, which can reflect whether a person's spirit or psychology is sound or not. Without eyes, it may mean poor spirit, unclear thinking or insight, and weak mind. Eyes are like ghosts, usually a sign of fear.
I dreamed that grandpa opened his hands and called me over: Opening his hands usually represents welcome, which is generally related to the relationship between people. What's your relationship with grandpa?
Your experience is the key to dream interpretation. Generally speaking, such dreams are generally related to changes, which may imply that some things are not over yet, hovering between the end and the beginning. What's changed recently? Are you eager to change? (The meaning of "change" here is extensive) Good luck!
Your eyes may refer to your grandfather, which may imply that you are worried that his old man is mentally ill.
I asked you to come over, and you agreed, which reflected the relationship between you. You care about each other, which shows the relationship to the next level, or you may subconsciously want to call you home to visit his old man's house.
Good luck!
