My client is feeling attacked again. She went to a group meditation and now feels she is back to square one. Why is this, and why is she seeing black spots in front of her eyes?

Unfortunately, she has picked up new attachments and they are manipulating her perceptions by impinging on the nervous system and this is something that is a target of opportunity they know how to perturb. It is not serious. It will not bring long-term harm. The key is to once again do a thorough clearing and cleansing and this will also amplify the karmic repair needed to help shore up her defenses overall. You can coach her on the need for requesting divine safety when doing any kind of intuitive work, and this includes meditation as well. Without requesting protection in advance, meditation carries risks as it is extending out the energy and that can be used as a bridge for outside beings to reenter by coupling with those energies when they are once again drawn back into the energy field. The reason she feels so badly, is these are spirits that have been deprived of energy for a time by becoming free-roaming and are quite desperate, and sometimes they are quite savage because of their desperation to get as much energy as quickly as they possibly can. So there is a high motivation to perturb their host as greatly as they can, to stir up fear, tension, and other negative emotions, as this is the energy they can use most readily. This simply needs more work and ongoing checks to reach a point where things are stable for a longer interval. That will bring reassurance as well, and will be seen as a successful outcome.
