Passed Father Dream

My father passed away September 21 of 2022. I've had a few dreams this year that had him in it. While I figured out what the other ones meant, the one I had last night is confusing me when I do my research. It contradicts itself. If anyone could let me know what it possibly means. I will tell you the main part.

I'm at a gas station with my sister, we are in this kind of van. We are parked next to a pump and she went in to pay. I'm standing outside and I hear my name. I look around and as I turn, I 3nd up seeing my dad. He's smiling and seems happy. My sister comes out and I start to kind of freak out. I say, "how is this possible, you are dead." My sister comes over and asks what's going on. I tell her that dad is here even though he's supposed to be dead. He starts to come near me and I run away. No matter where I am going, he follows and every once in awhile I can hear him call my name. It gets to a point where I no longer see or hear him but I still feel his presence and I keep trying to get away.

There was more to the dream but that was the main part that stuck out to me and I'm really at a loss as to what it could mean. If anyone could help, please do... Thanks
