It is not being dramatic to feel you may be under psychic attack or have picked up unwanted energies by visiting certain places or being in the company of certain lower energy individuals. Energetically protecting or shielding yourself is as important as taking a shower or a bath daily.
To shield yourself, just imagine, think or visualise yourself completely enveloped in whatever colour light you choose. You can also shield others or objects such as vehicles or homes with light. Shields do ware off so it is important to repeat this process daily.
