Stowaway Spirits

There are spirits, thought forms and entities which exist in other planes of existence that can attach to a part of you in that dimension if you do not protect your energy body - especially if you have a low vibrational frequency (if you are emotionally distraught, generally exhausted, depressed, have a negative mindset, a blocked energy system etc).  Trapped spirits can also be attracted to people of light because they believe the person of light can help them if they are stuck.

This may alarm some people, but it is better to be aware so you can do something about it instead of be affected by a potentially wayward being.  Beings can also be benign and are just looking for help.  The affects of spirit attachment can vary from no obvious impact on you to making your life miserable.

Sometimes, you can tell if someone has latched on to you if you find yourself doing or saying things which are uncharacteristic for you.  Also, you may have feelings you cannot explain.  However, some beings or thought forms can be entangled energetically for many lifetimes, or to a lineage, so you may not even notice they are there because they have always been there as far as you are concerned.

One way to protect yourself energetically on a daily basis is to ask Archangel Michael to protect you from any beings which do not serve your highest and best.

Some believe that you can do more harm than good if you try to clear entities yourself (for yourself or others) if you are not adept at working with energy and do not have the knowledge to properly protect yourself and others.  If you are concerned, seek out a legitimate healer or psychic to help you (this should not cost hundreds or thousands of dollars).  In any clearing, ensure that energy is transmuted into the light so that it does not attach to someone else.

I personally believe that we can clear our energy bodies to the point where we vibrate at a level where we are no longer affected by lower frequency beings and thought forms.  Just like there are light frequencies beyond the visible light spectrum for humans (IR and UV) or different radio stations; say changing from am to fm radio which is a different band of frequencies altogether.
