Has anyone been able to visualize 4-dimensional objects while on amphetamines? I felt like I could almost visualize the hypercube or 4-simplex in very brief glimpses when I was taking Benzedrex regularly (I've had some of the same phenomenon recently too even though I haven't been taking it). What drugs would be most helpful for attempting this and what doses? Also what other procedures would you suggest employing to achieve this goal?
