Regarding Paganism it's a very large umbrella term for numerous Pagan faiths. Some are very modern such as Wicca (Neo-Paganism as a movement really only began as such in the twentieth century, although it does have roots and influences from the earlier pagan practices of before.
Some people practice forms of paganism specific to particular pantheons and cultures. Some of those practices and beliefs have survived as living traditions and there is now a revival of sorts going on. Personally, I am more interested in pursuing Celtic paganism, as a I have more of an interest in the Irish and Welsh deities, but obviously I don't restrict myself to deities from those pantheons.
An occultist would be anyone who practices some form of occultism and who identifies themselves as such. Occultism covers a broad area of subjects - magic/witchcraft, divination, various kinds of spirit work, necromancy, etc.
Re. Mercury and Venus, I don't know that it was a communication from them, it's a matter of belief. After reading the Orphic hymns to them and giving offerings, I meditated and asked them to communicate with me. I'm trying to hone my psychic/clairaudience senses in order to better perceive communication from spirits of all kinds.
All I can say is that when seeking communication with deities and trying to get into a light trance, there have been some occasions when words and phrases have come into my head - and it doesn't FEEL like it's come from my own mind/consciousness. It just feels different, such as when I asked Hekate for advice as to how I might get better at communicating with the dead and I received the advice "Spend more time in cemeteries."
