Greedy Goblin

Ok, so first things first, I'm not a physicist or scientist in any way (software developer by trade). I love science (from astronomy to quantum mechanics to machine learning), but very much from a layman's perspective. Secondly... this is bizarre... hence why I'm posting in the "speculations/pseudo-science" channel, but could definitely use the help of someone properly qualified and with far more knowledge than me to try and make sense of a bizarre dream I had last night (if there is any sense to be made from it that is!). So my dream started with some kind of geometric structure (material seemed like hard plastic/polycarbonate) being loaded with 3 concrete blocks while suspended over a fast flowing river. The geometric nature of the structure somehow allowed it to self-balance the 3 concrete blocks as if they adhered to it's structure, without being physically fixed/attached. I seem to recall the central structure rotating in a haphazard, jolty fashion, but the concrete blocks never fell off. The blocks had to be loaded at the same time for it to work. Once they were placed on, the structure started to slowly traverse the river, suspended just above it (occasionally dipping partially into the river). Then I remember someone (not sure if it was me or someone else) talking about how it exhibited "ricep/rycep" behaviour. Also notable was the sense that the central supporting structure was much lighter than the concrete blocks. So on waking, I searched for references to "rycep" and "ricep"; nothing came up for the former, but I did come across "rICEP" which apparently stands for "Reverse Induced-Charge Electrophoresis": https://core.ac.uk/download/pdf/79710808.pdf I tried making sense of some of the above paper but it's way beyond me! 😅 And elements of my dream, certainly if taken metaphorically, could be related to "electrophoresis"... the geometric structure and concrete blocks representing particles and the river being the fluid in which the particle was "suspended" but also maybe representing the electrical current and the motion relating to electrophoresis??? The utterly bizarre thing is... I had never heard of electrophoresis before my dream and certainly never "rICEP"?!?! 😲 So, if there's anyone out there for which this makes any sense, I'd love to get your feedback!
