I flew on Dreamliner a few times great Aircraft. Aisle seats are a no no for me whatever Aircraft you're on. If its a long haul you might try and sleep but people have a habit of brushing past you if your arm is on the arm of the Aisle seat or the Trolly dolly smashes into you if you are not in your little space ie not overhanging on the Aisle. The cabin lights on my Gulf Air flight into Bkk were dimmed with a light show including purple, yellow, and blue lighting throughout the Cabin Soothing.
