i agree look up dali
its something thats doesnt look quite right or real.. like a skull with a train going through it etc..

Some say “bizarre” is super real in that the inside thoughts and visions of the actor are integrated into the “depiction.” But what is vital, maybe, is that Surrealism was only one of a number of schedule that explored a new reality in the early years of the 20th century. It’s the one that seems to have stuck by way of it’s disturbing descriptions. Salavador Dali came to the movement late but his showy personality basically overran the additional artists and that’s the one we all reckon of when the S word is mentioned.
As to how do you draw it. You can’t really make it up or it will look like someone else’s (mainly a terrible Dali or a knock-off.) Keep in mind that Dali was painting during the Spanish Civil War (when his most memorable paintings were made.) He was painting (perhaps) his relationship to the destruction and atrocities around him. (Check out “Guernica” by Picasso, too). Dali used his ability to render objects in paint to make impossible figures and landscapes but that was his vocabulary.
There are additional ways but they have to come from your explorations.
Hope this helps a modest.
