My grandfather passed away about 2 years ago, maybe 3, dont remember; but about a month after he died, he appeared in my dreams about 4 times to this day. Usually just asks how's it going with my life. Pretty much checking on me, really. My belief is.. it's not something yer subconscious would cook up however much potential it can do so, it's actually spiritual in nature.
I agree. And I also always thought that its a way that whoever it is that has passed on can comfort you through hard times. It also tells you that you are not alone. If you have heard this before, my apologies. I have never had this experience myself that I know of. Cause I have had many dreams and actually small premonitions. They are rare but they happen.
Sometimes people show up in dreams that have already passed on to show you how to get through whatever difficulties lie ahead.
If you think you need more insite then let me know. I May be able to help.
