Nice grow! Glad to see more blueberry hashplant grows out there! 
It’s a legendary strain that more people need to grow out and share. I asked bodhi awhile back about whether or not he’d be cool with me doing a preservation of the BBHP (graciously donated by @The_Lazy_Hippie), and his cheeky answer was (paraphrased), “I’d appreciate it if not - I might remake any of the 88g13hp crosses anytime” and then a month or two later he posted pics of an 88g13hp seed run with unknown moms. Hopefully bbhp makes a comeback!
bodhi’s only used one Blue Dream cut and it’s always been the Santa Cruz cut. I think he talked about it in one of his interviews. So the answer is, yep, Dream Lotus = Blue Dream (Santa Cruz sativa cut) x Snow Lotus. 
Reason for edit: Changing 88g13hp to Snow Lotus since @The_Lazy_Hippie pointed out my mistake.
