Thanks Alotofchoo for sharing with honesty about these experiences. I really think that it is very possible that it might be your loving grandmother looking out for you that is visiting like a spiritual guide.
I have had many encounters myself trough my life.
Advise...since we can not know for sure though, i suggest you not pursue to try to contact her on your own...it is best for the passed to be resting in peace unless they wish to look out for us on their own.
Also, you are very lucky this encounter was peaceful and loving, but not all are...try to control your curiosity and not to try to contact other ones as it can be dangerous and even make you pretty ill if you encounter an hostile one and some are tricksters.
