Yes. Many people report that during a truffle session it becomes easier to connect with their feelings, as usual mental chatter can quiet down and emotions may feel more vivid.
It is also common for buried or overlooked emotions to surface. This can offer a chance to notice, explore, and reflect, though experiences vary from person to person.
Set and setting matter. Go in with a clear intention, choose a comfortable and safe space, and consider a trusted sitter. If emotions feel intense, try slow breathing, open your eyes, change posture, or take a brief pause.
