When Speedsters die they become one with the Speed Force. With Barry this isn't the case for starters since he wasn't connected to it at the time and was only just getting his connection back, secondly if Barry was dead Team Flash would have a Time Paradox on their hands due to the fact the battle of 2024 wouldn't come to pass and Professor Zoom would be able to kill Barry as a child with nobody to stop him, next the only way I've known a Speedster to merge with the Speed Force while they're still alive is during the Crisis on Infinite Earth's storyline where Barry runs so fast he merges with the Speed Force forever but in the case of the Particle Accelerator he wasn't moving at all, Finally I think his disappearance is to do with this new Meta-Human which IMO is the Mirror Master who can send himself and others into an alternate dimension from any reflective surface, his Mirror Technology also allows him to use Illusion Casting/Projection which generates illusions from the user's/victims mind which can explain what Barry is experiencing in the Promo because these illusions don't just affect sight, they can resemble touch, smell, taste, and hearing. The only thing that gets me about this is that Mirror Master isn't a Meta-Human he could only send someone to the Mirror Dimension with his Mirror Gun, but then again Pre-New 52 Weather Wizard could only manipulate the Weather with the Weather Wand, but in the series he can manipulate it of his own free will.
