The best links to click while you're stoned! Psychedelic, mindfucking, mesmerizing, reality-distorting or trippy games, video, audio & images that make a sober person feel stoned, or stoned person trip harder! Come for mindfucks and self-inflicted gaslighting. Or the hypnotic or mesmerising. Vivid colors, intense patterns. Mind-blowing science and philosophy. Chill or trippy music. Surrealism, absurdism and strangeness. Reminder: This is not a "reaction subreddit".
