Your concern is a relatively common one. I receive many letters from individuals who have used an illicit drug and subsequently developed similar side effects. The side effects are frightening and psychologically damaging. These repeated negative experiences underscore why drug use is so dangerous.
Psychoactive drugs have a physical effect upon the brain. When we consume a substance, it enters our blood stream. There is a protective mechanism in the body called the blood-brain barrier. This barrier keeps unhealthy substances from entering the brain. It is almost 100 percent efficient, but some substances get through. These are the psychoactive substances. They change the brain chemistry. Users hope the change is temporary but that may not always be the case. Drug usage is dangerous. It’s a risk and any user needs to consider that risk. Can drug usage cause serious psychological problems? Yes, undoubtedly so.
If you are currently using illicit drugs, then stop immediately. I would also suggest being evaluated by a mental health professional. A mental health professional could gather a detailed psychosocial personal history and determine what may be wrong. He or she can also provide the appropriate psychosocial intervention to assist you with your symptoms. During the evaluation, a mental health professional may also suggest that you see a psychiatrist. A psychiatrist may prescribe a medication to assist with your anxiety and your “dream-like” symptoms.
I understand that dealing with your symptoms is difficult. It is important to see a professional. It is the right course of action. Please take care.
