Dreaming of a laboratory indicates that we may need to make a more objective or perhaps scientific (knowledgeable) assessment of what is going on in our lives. A laboratory can suggest a very ordered existence, and it will depend on whether we are working in or are specimens in a laboratory how we interpret the dream. To be a specimen suggests that we feel we are being monitored in some way. Dreaming of working in a laboratory indicates that we need to be more ordered in our approach to life. We may have certain talents that need to be developed in an objective fashion, or we may need to develop our thinking faculty further. You might like to consult the entry for Invent/Inventor.
