Lacey,
What you are describing are classic signs of sensitivity and Awakening. They are also classic signs of early stage schizophrenia.
Only you can truly determine which it is.
The next time you go into that state (and you should definitley go there again when you're in the right frame of mind to do so) make sure and protect yourself first. ElleWmhhw has mentioned a very strong method that obviously works well for her.
ANother, very similar option would be to quiet your mind just enough to get the background noise out, but not so much that you open the channel you did last time. In that quiet space, picture covering yourself in pure white or golden light. Envision this light as a protective force that will repel anyone or anything that may wish you ill will. Envision it as a filter that will only let in positive, loving energy.
When you have covered yourself in Light, go deeper into your open channel and ask for your Benefactor to come to you. I suspect you will encounter either the voice that snapped you out of your last situation, or a female form of some kind.
If none of these things happen, seek the help of a Healer or Medicine Person. If they cannot help you, you should probably see a counselor. I don't mean to be flippant or condescending, but schizophrenia is a serious condition that often manifests itself in a person's late twenties, early thirties after several years of "odd" feelings and "encounters".
One should never discount the mundane explanation in favor of a spiritual one without first eliminating the Mundane as a possibility.
All that being said, you may have a very strong gift for connecting to spirits, Angels, Allies and/or Guides. If this is the case, that gift should be nurtured and grown: preferably with the aid of a teacher or mentor.
Good luck!
