Strange Question (No ridiculous answers please)?

Okay, where to start! Ever since I can remember, I have always been in tune with my emotions and intuition. High school is where my intuition really started kicking up. We had a guest speaker come in and talk about her son who overdosed and I just felt so sad. I felt like I was connected to him in a way and I could just feel him around in the room. After that event, nothing really happened until my grandma moved in with her boyfriend (this year). My grandma and I were watching tv when I got a very overwhelming feeling and it felt like someone was right next to me. It was really uncomfortable, I have never experienced something like this in my life before. I tried brushing it off but then images started popping into my head of a petite, blonde haired girl and the name "Jessica" was shown to me in my head. I found out that my grandmas boyfriends daughter passed away in a car crash 18 years ago and her name was Jessica. I was shown a picture and she was blonde and petite. The other day, I was checking out a lady at the register and she had a baby. I saw a quick image of a lady holding her pregnant belly and smiling but it was being shown to me, like someone was holding it in font of my face. When the lady walked away, I heard "abuela" in my head which means "Grandma" in spanish. All I want to know is how to go about telling people that their loved ones are coming through. I am extremely terrified to go up and end up being wrong so I just need a little guidance! Thank you!
