Hi all, so sorry to be late in responding to this! I'm just now catching up with the forum, yada yada yada... Anyway, here I am and I think I understand what you're saying happened to you,
June. A couple of things come to mind.
1. You have more than one higher self, as I understand the concept, and as I have experienced. During periods of intense personal evolution, you may find that you have a "new" HS, as one level of guidance needs to shift into a higher level, and thus a new HS steps in. That's what happened with me when I was moving from sheeple-consciousness to awakened and aware. Sometimes I'd ask if it was better that I have a new HS, and my guides would seem to confer about it and a new one would come in (always thanks said to the last one). This idea of replacing one's own HS really bent my brain in a new direction, and was a strange new thing to understand, but the reality of it was right there in practice, so there's something to it, I suppose!
So now, my main guide-in-contact seems to be Anica, who describes herself as my "chosen future perfected self". I don't think she is my HS specifically, but a higher-dimensional aspect of self. Maybe that's nitpicking, but when I check in about it, it seems there's a distinction.
2. It could be that some being from the future (perhaps a future-self aspect, or a friend or teacher) was visiting you with a book in hand, suggesting that it would be good for you to read it, but that you would be reading it later. Maybe they came at an early point to give you the anchor that would later create a connection to spotlight something for you to focus on, as you are right now in distinguishing between HS and Pleiadian visitor. So in that sense, it "feels" to me that rather than brushing you off, she was saying it's not the time for you to read this now, but you'll meet me again when you do read it later on.
3. Extended non-terrestrial family from our stellar lineage sometimes visit. Since they are connected via DNA, which is as much interdimensional as it is molecular matter, their appearance can be profoundly "in your face" so to speak... they may appear as nearly real, though luminous/numinous, and very complete. The family connection is strong between Earth humans and Pleiadian humans (and there are Pleiadian humans in many planetary systems, so there is a wide variety in their appearance).
It's funny to me, how she brushed off your comment about her appearing beautiful. Asket's like that
Especially in the early days of my contact with her, she's like "let's get to business, I've no time to waste". At first I thought I'd disappointed her! Really, I think Pleiadians who appear in this way really want to get us awake and then get out of the way so we can get busy ourselves. The last thing they want is for us to be lolling about worshipping them. In what I've experienced, they tend to nip that sort of thing in the bud.
I hope this is helpful! If you've any specific things to ask, please do
