I’ll jump on the bandwagon. Don’t do it. Well, do what you want. But be prepared for massive reconciliation.
I did this a few weeks ago out of curiosity. I have 3 separate computers in my office.
I put 2 different subs on each using iTunes with a “shuffle” playlist on each. So 3 subs playing at once, but with a a total of 8 possible configurations (2^3)
Suffice to say that was a shitty 2-3 days all around. Massive headaches, angst, reconciliation, thoughts of “HOW DID I FUCK UP MY LIFE?”
That experiment did not last long.
Even as of late, I’ve completely stopped doing any looping of subs and stopped completely with listening to them while asleep.
I turned off auto-repeat. I have my subs in iTunes and will listen to one (on ultra on the office. Masked distracts me too much whilst working).
I then let it play (whatever sub it is)…then when I consciously notice that it’s over, I’ll start something else for a single loop. No set plan as to which subs…just whichever seems appropriate for the moment.
My dreams have skyrocketed in vividness even beyond what I got when listening to Mind’s Eye Terminus Squared while sleeping. And that is saying a TON.
tl;dr: Don’t do it…Don’t overload yourself.
