Why do I keep dreaming of my mom, who recently passed away from cancer, still being sick and in pain?

My interpretation of her unresolved thought (that’s what I think it was, perhaps, I’m a student of divination independently) is:

Perhaps Nathan is the devil in the future but is actually a nice person who people don’t comprehend due to the intelligence required to do things like cure cancer.

She probably had a son who carries genes for anti-cancer.

Maybe Nathan really likes boobs which is honest if he is trying to cure cancer and opposites attract.

The second option if the cancer is not even noticed yet is to wear the Immortality t-shirt, however, immortality is preventative, it is not good to wear this if one thinks the cancer is noticeable.

That’s my guess at the moment. Honestly.

Perhaps Nathan has the cure for cancer and she was not sure if she should use it.

I have a psychic personality type and have studied omniscience extensively. I live near Yale and my dad has a Yale PhD. My mother was also a genius by most standards.

Or possibly she thought Nathan was the devil and didn’t resolve her thoughts on that.

I’m an impartial person, I’m not trying to hurt feelings all the time.

I would advise if your goal is to cure someone else’s cancer other than your mothers’, whatever kind it is the Immunity shirt Nathan designed may provide a solution, though entropy will say it’s inadvisable. It is not a medical solution so one should expect for it to do nothing, just wear it hoping it might be lucky there might be no result. You will probably forget the cancer was ever important.
