Greetings Mr B,
Welcome to this site!
Maybe this is a spiritual breakthrough for you--getting a glimpse of the beauty and natural harmony that is the basis of afterlife realms?
Were these women casting spells on anyone? If not, I don't think the idea of wiccans and druids is neceessary, as there are all kinds of souls in the afterlife. They sound more like they were just enjoying their time and probably were there to welcome you.
If you will keep an open mind to this experience, you will probably begin to have more such visions as you get attuned to how close the spiritual realms are now to our physical world. this is natural and good, a sign of our times.
If you want to be better prepared for such visions/ events, you can read the articles by Bruce Moen that are listed across the top of the index. He's already had such experiences and describes his explorations very helpfully.
