TwoRue its happend to lots of people!
the thing is your consciousness knows it gonna have a dimensional experience
and it link, connect to that parallel reality that your already in the spirit realm.
its like a de ja vu, when you experience in the present a moment that in the future.
in fact when you imagine and feel the feeling that you have under any influence,
the mind act like its you take them, no matter if you experience it the same or not,
the fact that the feeling the same means the mind acting like your under the influence.
there is some science research about athlete that put in mri's and other body measurements
and they tell to the athlete to imagine that the do there sport activities and they
found out that the brain sand electrical pulse to the muscle JUST LIKE IN THE REAL ACTIVITIES!!!
so when your imagine and feel that you take spice your brain release spice just like when you smoke or drink it!!!
one example that i have in my personal live is in the day that i have my first aya seremony
in the morning of it i did my reiki session just like every day but in this session
i see a jaguar witch is one of the 2 common animal spirits that you see in aya
and i was completely sober when doing the reiki session.
the fact you notice it mean you consciousness are open and that is only the start of
the "magic" to happen in your daily life!!!!
though the minds may be different, the body forms may be different
it is through the heart that we recognize our spirits are one.
everything im writing is a complete fiction and it is only a reflection of my imagination.
