Do you meditate? If you do or are interested you can go on like Utube and look up spirit guide meditations. You can fallow along and do it with the video but some people think of that as hypnosis and if that makes you uncomfortable than listen to it and preform on your own. This is how i had my first experience with my guides. My cousin can now go into the meditation alone and fast and connect with one of her guides.
I do believe that your grandpa can be guiding you but he isnt the only one and not the first
