First of all an apology for not being on here recently. Someone said "Smile. Things could be worse." So I did smile, and, yep, things were worse. A massive flare-up of my illness followed by a series of "after shocks", my Mum suddenly went blind in one eye, and a cousin who went in to have a hernia operation is back in to have the mess created by the first surgeon sorted out. As my cousin is 65, an only child, and never got married, I'm the only blood relative he has got, so when he is in hospital I'm the only visitor he gets, which, given my own illness, is difficult for me to achieve and also get on to this forum.
Anyway, back to topic.... The only pleasure I can have during flare-ups is reading, and I've been reading "The Drug and Other Stories" by Aleister Crowley (Wordsworth Editions ISBN 978-1-84022-638-6) and one of the stories is "The Testament Of Magdalen Blair" first published in March 1913 from which I quote: "There are always at least two of us! The one who feels and the one who knows are not radically one person. This double personality is enormously accentuated at death. Another point was that the time-sense....was decidedly deranged..." and "Still more was this the case in the process of his assimilation by the 'demon'."
So Tony, it looks like your ideas of two personalities, and the Daemon is nearly 100 years old. Could you be the reincarnation of Aleister Crowley? He died 7 years before you were born, which, if I understand reincarnation theory, is about right.
