Hello
The symptoms describe suggest some type of sleep related hallucinations. They are a type of parasomnia. They are mainly visual, but may also involve sound, touch and taste and smell sensations.
They are usually seen in teenagers and young adults as well as in older people. They may be related to alcohol, anxiety, mood disorders, insomnia or some current medication. In case your symptoms are associated with severe daytime sleepiness, then you may have narcolepsy.
Sleep related hallucinations however, tend to resolve with time, many a times requiring no treatment at all. You should maintain proper sleep hygiene and avoid alcohol.
You should consult a sleep specialist. Based on your complete medical, psychiatric, and sleep history, he may prescribe you some medication which best suits you.
Do keep us posted on your progress.
Good luck.
While your post itself only touches on the coorelation between your symptoms and sleep, you've chosen to post this in a sleeping forum, so I'm going to go out on a limb and recommend you look up hypnagogic illusions.
