Working out the meaning of something I had picked up resulted in a brightness behind the closed eyelids.
This happened twice this morning.just like opening shutters in a dark room.
Somewhere in journal I'd written of experiencing this during an informative dream experience and reading later how Kurt Leland saw this happen to a lady he was witnessing in the dream zone trying to work a puzzle out and when she was correct the room would get lighter. This was confirmation that this was right.

This happened after I woke up to 'think of a poppy'.

( through the day a lady had told me that she adores poppies.I thought no more of the comment)

Thought I should have to look this up in morning but decided I must think of what it means to me now, not what a book says. I thought of Rememberence day and poppies so decided that poppies remind me of people who have died during wars.
As I thought this the brightness behind eyelids happened. Lay semi awake when I picked up

" her husband was found dead in a field".

Immediately I thought of the time I felt I was being shown past lives when I saw a picture of what seemed to be going back centuries ago with strange carriages and men with strange pointed metal hats on. This was a battle and there were dead bodies on the ground in a battle field but I felt immense sadness for a young man lying on the ground amongst other bodies but my feelings were for the people who would feel the sadness of his death.
I was awake now and thought this through wondering if this was all connected when the lightness started up again.
So Ive had this in the dream state before but this is first for awake but dozy.

Back to sleep and just after a dream that I've got a chemistry exam tomorrow and haven't prepared for it ( could just be to do with all Im wanting to learn) my dream finishes with watching about 15-20 men walking towards me. They all had black suites on.But it was the black that was noticeable and got me staring. The black was blacker than black. They wore the blackest colour you could imagine a black to be. They are now standing to the side of me.
I woke up and thought this last bit through and suddenly came to the idea of MEN IN BLACK from the film.
I only ever saw the first film so this morning I googled to remind myself what exactly it was about.

I wonder if they could represent what Robert calls Gatekeepers.Other authors write of similar energies representing almost a look out to prevent dreamers entering areas that we shouldn't enter. As kurt says he was told they cannt let dreamers into designated areas where they could cause havoc because of their behaviour due to their dreaming mind.
Also , just the desire to visit somewhere is not enough for entry. I think Ive had this before but in the form of black robot type characters.
I just love the humour, whether it was my subconscious creating these or other I just love the humour.
