It sounds as though you are having nightmares. If you awaken that easily you are likely in REM sleep. REM is a very light stage of sleep and dreams are most vivid. If there are formed objects in your dreams and if you are not screaming out this is not likely a night terror. Treatment is available for both disorders. If you have these "hallucinations" as you are falling asleep, we call it hypnagogic hallucinations. These are commonly present in narcolepsy.
Those symptoms are suggestive of a disorder and you should contact a local board certified sleep specialist. These occurrences are surely disturbing to you and inconvenient.
