Can meditation be harmful?

I often see promotion of the positive benefits of meditation in the media and even in school and government settings. However, there is evidence meditation is not always beneficial. https://www.psychologytoday.com/us/blog/the-science-behind-behavior/201604/the-little-known-downsides-mindfulness-practice Is there much discussion of the possible negative aspects of meditation in Buddism? For instance, could it leave one susceptible to malicious spirits?
