LSD: Dream Emulator is an exploration video game developed by Outside Directors Company and published by Asmik Ace Entertainment for the Playstation. The concept for the game was based on OSD employee Hiroko Nishikawa's dream diary, which she kept for over a decade. The diary was released as a book called Lovely Sweet Dream to go along with the game.


The game released in Japan on 22 October 1998, alongside the music CD LSD and Remixes, the previously mentioned book, and a bonus one-song music CD titled Lucy in the Sky with Dynamites bundled with limited copies.

On August 11, 2010, the game was re-released on the Japanese PlayStation Store under the PS1 Classics section, for ¥617 (equivalent to $5 at the time). This version received a D (17+) rating from CERO (the Japanese equivalent of the ESRB or PEGI).

LSD: Dream Emulator has gained a cult following because of its surreal contents and its scarcity, commonly placed in the top 5 on lists of the rarest/most expensive PlayStation games. Copies on eBay range in price from $700-$1,500.

Limited/Normal edition discrepancy

Numerous marketing materials advertise the game to have two versions: a limited version including the bonus CD and a normal version which does not have the bonus CD; however all ~200 copies documented since the early 2000's have been the limited edition. This paradoxically implies that the "normal" release had less copies produced than the limited edition and may not even exist.

A PlayStation archival website makes the distinction between the limited edition (SLPS-01556) and normal edition (supposedly with the ID number SLPS-01642), which only raises more questions as the ID given to the normal version would mean Sony catalogued it after the limited version.


The game takes place in a first-person perspective in a 3D surreal environment. The player's "goal" is to explore said environments. The controls are tank controls; the player can move forwards or backwards, turn, strafe, run, look up and behind.

The game is played in short sequences or "dreams". The initial location of each dream is randomized. The player can access other environments by bumping into objects or going through tunnels, a mechanic named "linking". Bumping into certain special objects, like animal and people, will result in a "stranger" dream.

The environments are usually the same, like a Japanese village or a house, but they may be populated by random objects and the default textures swapped with other textures.

Each dream can be about 10 minutes long, then the player will "wake up". However, if the player falls off a pit or a hole, the dream will be cut short.

After a dream, another "day" passes in-game, and the dream is marked in a graph. The graph rates the dreams in relation to it being an Upper, Downer, Static or Dynamic dream. The more the player plays the game, the textures of the environments change more often. Also, there's the possibility of encountering the Spy, who removes the ability to recall a dream in Flashback.

After a certain number of days, the Flashback option will appear. It allows the player to play an abbreviated version of the last dream they played.

Sometimes, a video or dream journal excerpt may take the place of a regular dream.


  • According to the foldable insert in copies of Linen Sampler, LSD was originally planned to release in autumn 1997.
  • Despite common belief, the flashing water visible in many emulations of the game is not the intended look and does not appear on real consoles.
