To dream of an experiment represents new ideas you are trying. You are taking a chance or seeing what happens. You may be merging different areas of your life or doing something you’ve never done before.
An experiment may reflect your curiosity or adventurous attitude.
Example: A man dreamed of seeing lab filled with experimental beakers. In real life he was having serious problems with his website business and was trying a number of different scripts to see if they would improve his website’s performance.
