When i smoked weed last night everything turned 4 dimmensional and my whole body was quivering. was it laced?

im a total pothead and have been for years now. i know all about marijuana and the effects. but last night was something ive never experienced from weed before. it was more of a trip than a high. ive done acid and shrooms and i would relate the feeling to something like that. i have a hunch that the saq i bought was laced with something but cant distinguish what it was laced with, any help????
