Mow-Your-Damn-L

Ok, so I've been smoking for about 3 years now, just the usual getting high and stuff. Some times I mix other drugs in with it (legal otc things) just for fun. I've done this a few times, no adverse effects, even at high doses of the other drug. Friday night I did this with some new weed I hadn't yet smoked. This was sold to me really cheap for quite a bit, but it was shake. I smoked it after injesting the other drug and was way way way more out of it than ever before. Then on Saturday I smoked the same ganj but mixed with a few small buds that my friend gave me. After the second time smoking (after eeating indian food, if that might have made this happen<?>) I began feeling really soaringly high. I started hearing things (i've heard its normal and called "getting the zombies") but then I saw things. This has only happened once before, when I smoked a bunch and then the 6th bowl was capped with opium and weed resin. The things I saw made me think of what one might see while on psybocilin or lsd or something. I saw a bullet hole in a sign (wasn't really there to begin with) rapidly yet smoothly change colors and then as I approached it the bullet hole didn't look bigger as it should while walking towards an object, rather the still color chaning star looking outcroppings kind of melded togeather into a wobbly circle. Then I passed it and it was gone. My girlfriend, a person who it takes alot to get high, not from tolerance but just because thats how she is, said she was alot higher than she should be off the small amount we smoked.

Basically my question is, in your veteran experience, do you think it was a) Just really ****ing good bud, b)Laced, or c) I'm going crazy (completely possible)

Thanks in advance.
