I was rewatching episode 3 where the real Dougie goes into the Red Room and Coop takes his place with Jade, between the two rides, and something struck me about the part where Dougie just kind of turns into a cloud of smoke and then there's a small gold orb and then a bigger, black, fleshy orb that starts to ooze something. It reminded me of imagery in Episode 8 of the Bob egg and the Laura orb.
I have to assume those different orbs are Lynchian short hand for good and evil or something to that effect. Dougie's gold orb about the same size as his black fleshy orb (so maybe Dougie was kind of a dick but not a terrible person?), whereas when we see the cute little kid get obliterated by Richard Horne in the pickup truck, it's only gold but it's more like a gas than a solid orb. Not sure if that signifies that's supposed to signify that humans all start out good natured or innocent but it's kind of influx from birth and open to corruption or something? Clearly there's a motif forming either way.
Remains of Dougie Jones
Golden cloud of the small kid
Bob orb and accompanying milieu
Giant's braingasm and Laura orb
Also I noticed there was a liquidy gold orb at the center of the atomic blast too
That one's a head-scratcher.
What got me thinking about this was I was listening to the Damn Fine Podcast for Ep. 10 at work and one of them floated the idea that maybe The Experiment was somehow Laura in the past or future or something, which he walked back pretty quick, but I found to be an interesting theory I had never considered before. I mean, Laura was in the Red Room and then she turned into a sheet and ascended to...somewhere not long before Cooper got out and the Experiment shows up in the box not long after Cooper. Probably not, but there's something about those fucking orbs...
