Ahsoka TV Series (Spoiler Discussion)

i think we need to get on the same page here. did anakin appear to her in a vision (doubtful imo)? did she actually travel to the world between worlds and meet anakin there (silly imo)? is everything "only" happening in her subconsciousness, symbolizing her struggle to stay alive (definitely the case imo)? there seems to be indication for all three, but a combination doesn't make much sense and if it's is just one of the three, some elements feel out of place.
