"@Surfer. Do you suspect that the different results could be that although you thought you purchased the same strain that in fact, you got a different variety or was your reactions just based on a different day?"

No, I'm referring to actually smoking from the same bud. I think that a lot has to do with a person's mood, pain level, etc. each time it's utilized. The same bud can produce different results.

I think I've mentioned it before, that sometimes a Sativa will knock me out and an Indica will raise my spirits. (opposite of what one would expect). Try your Blue Dream sometime and see if you like it. It shouldn't be a dramatic difference to you.

It makes sense to make your own butter to monitor the strength. Btw, in case you didn't know it, you just need inexpensive trimmings to make butter, not the buds.
