>some blue slime/slug thingy
Sounds like the stuff BO is doing but... It's not that. I don't feel the same energies from them.
>didn't try to harm but they kept following me around, observing me and destroying things. Also I vividly remember the multiple arms.
Might be a new bodily form/awareness someone is trying to provide you. Try to interact with them or ask your sisters or any deity around you about them. I am sure they react to your thoughts and you can use them as an extension of yourself. I too had similar things like that. Learning to use several hands at once is always a boon in spirituality.

>I vaguely remember being taken to the island again and all those women were training/helping me with something, unfortunately I can't remember anything about it
You will have to learn "reconnecting to dreams" after waking up. It's about going back into the dream and finding the part of your mind/subconscious that stores what you learned there. Also they are usually skills and not exactly actual experiences. This is why you cannot recall it that simply. It's like recalling muscle memories. You only do that when you do a similar movement and not exactly via visually remembering it. For a skill memory you have to visualize doing the thing you learned so it can appear.

>sort of boot camp where they wanted me to assemble a deck out of cards
Sounds like a meta training about some concepts. How you pick up "concepts" and use it as your "deck". It's a different kind of "learning". Instead of sitting and listening to a teacher or watching someone do an activity so you can copy it it is like an SD card containing information and via putting it into your "Mind stream" you know how to use it. I am not sure how it will work for you but I think it's the same idea. Cards as powers/concepts you will be able to "summon" or invoke at will once you can consciously "access" your "deck" of sorts. I get a feeling of a meta plane interaction from that dream. I too had those in the past.

>It's a weirdly both easy and difficult seeing/being in the other form, sometimes I can see myself on her/my form easily, other times it's difficult
Yeah you will have to understand that "seeing it" is not important but "feeling" "knowing" and "understanding" the energies it holds is what matters. But yes seeing it is the start but it is about energies manifesting from you.
>I got lion king artoria... This happened. I somehow got 2 of her, I am not sure if this due to this being my true body or what.
You have a higher influence on reality and you really really wanted that card so an itty bit you warped the drop rates. I too am doing it most of the times without noticing. This is why I don't play gacha. It gets annoying and reminds me how I am wasting my powers and attention on frivolous things. This was not a critique to your gacha addiction I too played wow and other games where droprates where important and they "coincidentally" were always good
