Laced weed?

Ive been smoking weed for about 3- 4 months now. i do it about every 2 weeks. everytime i smoke i know my high. i get giddy i laugh alot and im really happy. never ever have gotten paranoid. like i seen people paranoid and high and i find it scary. but i get a happy high always and i cud say i smoked about 10 times in the last 3 or 4 months and thats the high i always get. Well the other day i smoked sum haze(never smoked haze before) and i got extremely extremely paranoid. where im layin down and i cant stay still. thinkin in my head dam they laced my weed. i kept feeling like my heart was gunna stop but it was all in my head. i was scared to sleep thinkin i wasnt gunna wake up. i was freakin out. i thought mayb i jus got a different high cuz i never smoked that type of weed b4 but then i kept thinkin it was laced cuz i had got it off of sum1 i didnt know. i could not stay still i kept twitchin n moving fidgeting around. i literally felt like i was just going to die i was soo paranoid. i wud touch my heart n feel it beating like it wud jus explode. was it in my head or was i really gunna die. i kept thinkin this.& I NEVER get like that im usually the happy high type were im so happy chilled n relaxed. I literally felt my hear slowing down but speeding up at the same time i kept feelin like i was gunna have a heartattack i was soo scared. i was really considering at the time to walk to the emergency room. my eyes were soooooo red n they never get that red.. o man jus writing bout it now makes me think bout how bugged out i was feeling it was so scary. soo i called my boyfriend and he told me to drink 2 cold glasses of milk eat sum munchies n watch tv and try and sleep it off. so i did so and i was fine in the morning. but i had really thought i wudnt wake up in the morning. and now im scared if it was laced im scared to smoke again cuz what if i get like that again .. i was also hallucinating sum weird things as well..i shudve just went to my normal dealer ..tell me what i shud do please
