You want to feel Spirits. Maybe the way someone feels the spirits depend on themselves..or the kind of psychic ability they have. For instance, an empath-an individual who perceives emotion may feel different a spirit, rather than a person who is able to sense energies around them and not emotion (it is different). Others may feel it like cold precense...
I have felt one spirit precense in my life only, when I was meditating. I was trying to Astral Project and a guy has been helping me.. I didn't felt him as cold, through emotions, being watched or something..I felt an actual spirit, an actual entity. Like a powerful precense next to me, the feeling was amazing!
Personally, I prefer always this kind of feeling of spirits, because it is a powerful way to know when spirits are around you-you feel their whole energy..and it's a powerful and an amazing feeling.
So if you want to feel spirits this way, develop this kind of psychic ability... I'm not sure if a spell can achieve that....
Personally I don't have develoled this kind of activity yet, however with meditation you tune yourself into these frequencies; spiritual frequencies. He was also trying to hell me; most likely the reason I felt him.
