Scientists have been working on technology that causes hallucinations, with no mind-altering substances to be seen.
People might still be trying to find a 40-year-old stash of LSD, but a team of researchers from Sussex University have opted for Virtual Reality and Google’s DeepDream system over acid for a 'trip'.
Apparently 12 volunteers experienced visuals similar to those caused by psilocybin - the ingredient in magic mushrooms - after being shown a panoramic video - altered by Deepdream - of the Sussex Uni campus, according to International Business Times.
DeepDream is described as a tool that "uses a convolutional neural network to find and enhance patterns in images."
Researchers said: "Overall, the Hallucination Machine provides a powerful new tool to complement the resurgence of research into altered states of consciousness."
