I've never done DMT but I have done 'shrooms and LSD many, many, many times.
I would recommend trying it. I've had several experiences with multiple people seeing the same imagery on DMT. Many people see a dancing woman at one point in their trip, for example. The most common visual on DMT is the "mandala" or "crysanthemum".
Terence Mckenna describes the crysanthemum as having orange and yellow petals, which I had seen firsthand before ever hearing Terence describe it. It was orange and yellow and looked as real as anything I'd ever seen.
It really is almost incomparable to shrooms or LSD..
