Dreams has three versions. The official version features the Cranberries performing the song in a nightclub. After which, Dolores O'Riordan heads out to a house where graverobbers dressed in black have placed in a very large tree pile. Dolores bathes the tree pile in water and a man is buried under the pile. The water frees him and in the final seconds of the video, the man wakes up.
The original version revolves around O'Riordan with the other band members flashing up throughout the video while she's sitting on in a chair with a cross as a back or a close up of her face and eyes. The video shows a mirrored image of O'Riordan to show she does the background vocals and towards the end the band members fade in and out constantly in front of O'Riordan.
Another version shows the Cranberries performing the song in a dimly-lit aquatic-themed room interspersed with shots of geometric flowers hitting water.
