A couple thoughts come to mind:
We seem to go through incarnation cycles, we have established what type of species to re-incarnate into to experience/evolve certain aspects of our selves, and will spend as many lives as nessasary in 'that classroom' to learn that.
When done we enter a new classroom which maybe a different species, different dimension or any number of things. It seems to me you're just ready to move on experience other things.
Another thought. The many random bits you pick up are likely what a friend of mine calls "Tuning into the high Band" Basically everything happening at the frequency we are at and resonate with we can hear in the quiet of our minds. We're just walking talking antenna's really.
I have picked up all manner of random things, I'm an artist so often tune into the Creative high Band and see random scenes from screen writers, novel writers, and even costume makers. Pretty awesome visuals.
It has no particular spiritual meaning - it just means our antenna is getting nicely clean and receiving well.
Discern what is of meaning for you and what is just random High Band pickups.
"Not fitting In" this is a product of the egoaic mind. When people get real they will admit they don't feel like they fit in and are either withdrawing from people as a result, following and trying to fit in as a result, or trying to get people to follow them.
The Cosmic Truth is we are All That Is. We belong where ever we want to be - we can't Not Fit In.
People may or may not be at a frequency that resonates with your being-ness, that just means you may not feel close connection with them due to disharmony of frequency - it doesn't mean you don't 'fit in". Try instead to look at where they are, connect to the aspect of you that has walked in their shoes learning what they are learning at some point in your many re-incarnations in this classroom.
Change the focus of the egoic mind saying it doesn't fit in, to the view of the Spirit which knows it chose to be here and has experienced much as the person before you has.
Find the Connection not the Disconnection.
