Dreams In Meditation?

I was in the bath while meditating. (Probably not very smart I know, but with two toddlers this is the only quiet time I get.) Suddenly I saw a big beautiful forest with tall trees and a bright blue sky. The sun was brightly shining down over a beautiful large river with Crystal clear water and perfectly laid rock. The birds were chirping, air was fresh. When I looked down the river I saw a white being standing on the same side as me in the distance. I then got an overwhelming feeling of love and comfort and the name Evelyn came to mind. Suddenly I was thinking about my grandma (who passed two years ago yesterday) and I flashed to her house. I was sitting on her porch and I looked across the table, and there she was with her arm stretch out and a smile on her face. She was handing me a fresh made peanut butter cookie. I then began seeing flashbacks of all the things we did together and the things she loved to do. Baking, dancing, driving around, ea ting ice cream, etc. Then I saw a knight tarot card on the table. (We normally played rummy together) I then began to cry as I smelled the way her house always smelled and I felt the love and protection I always had when I was in her home and around her. She then looked at me and smiled, told me she loved me very much. And as I was walking out of her front door I turned and looked at her one last time and she said with a smile "don't do anything I wouldn't do" this was our saying to each other every time I left. I then flashed back to the river, and the white being was wrapping her arms around me to give me comfort. She then wiped my tears, and I could almost feel her hand on my cheek. I then asked if I would be able to see all my other loved ones that have passed and she simply replied yes, and their faces began coming to Crystal clear. I then flashed to some memories I had with each of them, as if I was physically there. (Many died when I was around the age of 10, I'm now 24) It then seemed like a good bye and I had this warm feeling, I then heard (mentally) if you need me I'm always right here. I then opened my eyes. Tears still running down my cheek. But somehow very relieved, with a great sense of comfort.

What did I experience? Did I fall asleep and have a very lucid dream, or was this a deep meditation? Looking for answers please!
