Strange experience that happened to me not long ago

I was at an event with my sister and my mother I didn’t know anyone so they were introducing me to people well we get to a woman I’ll call Jennifer and when I shook her hand I immediately felt like I was going to throw up I felt like I’d been hit in the stomach she said “my name is Jennifer but I’m pretty sure you and I already know each other” and I responded back “yeah I felt that as well” she then turns and whispered something to her husband and they both just stand there looking at me and she smiles really quick and says please help save us some seats so we can all sit together I said sure thing and I’m looking around like did anyone else see this just happen and I notice my mom and sister down the way so I start asking my mom about “Jennifer” and I told her what happened and she said oh yeah she’s psychic I said no what I felt from this woman felt dark and unnatural it wasn’t good and my sister said maybe it’s because you both have abilities but idk does anyone have any input on this? Thank you
