Starting dreaming again last night?

I don't think I've had dreams in my sleep since I've started smoking, and last night I had crazy dreams all night. For the first time in a while I woke up tired, like 2 hours later than normal. I understand this being a symptoms experienced during a T-break, but I've been smoking as normal just tried a new strain yesterday. Could it be strain related? Also curious in general of everyone's experiences with sleep and smoking, because more than anything else I've noticed my sleep pattern becoming regular and I'm not tired in the middle of the day anymore since I started.
