How can I unlock the psychedelic side of mdma? (safely)

When I do mdma, I never get any psychedelic hallucinations unless I take a high dose. But even then, I only get extremely mild and barely noticeable hallucinations. When I cross weed with it, nothing changes. People talk about getting mushroom like visuals when crossing them. Are there any ways I can get proper/strong hallucinations on mdma without taking an insane amount?
