I saw a dead relative I’ve never met in my dreams

For backstory I take these tylenol PM pills to help me sleep at night. Last night I had some of the craziest dreams and they were all over the place, but one part really got to me. I stumbled across this guy who was able to revive people, and he was reviving people who had only passed recently. I asked him if he could revive my uncle Anthony, who had passed over 50 years ago when he was really young. When he did revive him, he was only 4 years old, and he said he didn’t recognize me. He then told me that I looked like my grandfather (his dad) and then followed up with advice and said he loved me. I have no idea what this means, but I could feel myself crying in my sleep. Any idea as to why he out of all people showed up? I’ve lost a few people close to me and I’m just curious why my uncle who even my dad never got to meet was the one to show up.
