An Acid Dreams Presentation is a logo that appears on YouTube which appears at the beginning of each video. On their YouTube channel it shows a zooming title in random color in the black background before the presentation begins.
In the Reaper Files version, it begins with random zooming photos of anything death related, which depends on the video presentation, then a bloody white rose background with the title.
None for the standard text version but it scare you little bit.
Nightmare for the Reaper Files version due to its zooming random photos of any death related place. Don't watch their videos at midnight.
