Take one of the shorter-lived 2C-x drugs and watch Flash Gordon and Heavy Metal.
My preferred combination is AMT and 25C-NBOME (VERY DANGEROUS TO DOSE WRONGLY) with some ethylphenidate. The sight of a rising sun turns from being saccharine to something "beyond man and time". The 25C-NBOME is less for unique effects and more for the fact that you could literally have months worth of trips (1x a week) in a tiny bag.
If you want an escape plan, have a benzo like clonezepam (sp?). It'll tranquilize you out of a nightmare if some fucked up shit appears.
And remember, the interesting thing about psychedelics isn't the "oneness with everything" bull that idiots talk about. That's just a temporary addictive feeling. One of the interesting parts is the enhanced capability for visual modeling and making connections. The other interesting part is that it makes you feel like a golden man Prometheus thing. You conjure up mythologies and struggles from just observing the local area outside.
Also take 200-400 mg of magnesium.
