Was my weed laced with something?

On Friday night I was with a couple friends and we had a joint rolled, so we smoked it obviously. I only took 4 hits and I was gone, but i feel like it was laced, I'm not a stoner but i've smoke weed quite a few times. So I feel like it was laced because when i was walking through a ditch it felt like i was moving in slow motion or i was swimming through the air, then i got really paranoid that there was a bear or someone going to kill me because i kept seeing thing in the dark, also my hands felt like icing sugar and the rest of my body was numb. I asked the guy who rolled it if there was anything in it and he said something but i blacked out.
