Something i allways encounter while not having smoked dmt for a while / and even my first time.
Is this huge feeling of being scared of the experience, even with all the trips i did so far.
But the moment i actually start to inhale it fades away, the fear will be gone when the trip starts, and when it ends, i cannot wait to do it again

...
So it can happen that for days and months i do not feel self assured enough to smoke dmt because of some reason i dont exactly understand, but when i take the step, i can't stop loving it and get in this loop and spent hours of the day doing dmt.
I heard McKenna saying that it doesnt work when you smoke it within half an hour or so of the previous trip, but it works for me, wait 10 minutes and i get back to hyperspace..
I hope you will have a good smoking method, like 'the machine' or something and just keep inhaling untill you are there

Because my first times i wasted too much on lightbulb methods etc..
I think if you are ready to see some bizarre things, i guess the dmt will guide u to this hyperspace and you just have to follow it because it is you that want to learn the experience, you cannot change the trip but you can change the feelings u have,
being with or without fear, totally open or closed for whats to come.
so i guess its important to let go of other thoughts, and u will be rewarded for that i am sure!
and i would do it alone ( if experienced with other psychedelics ) or maybe just 1 sitter that is in another room ( when i smoke it with someone around in the same room, i cannot focus totally on the dmt trip )
Anyway it will be your experience, and yours only, and probably a wonderful one

if you show the respect it deserves, it shows you its capabilities.
Enjoy your flight!
