Altered state of consciousness induced by FLS with music. FLS significantly increased ratings for 22 of the 29 items used in the visual analog scale. Bars represent the mean and SEM; *p < 0.05, **p < 0.001 after FDR correction for multiple comparisons. The same questionnaire items as the original study were included [see Supplementary material in Kaelen et al. (2015)] to enable a direct comparison to LSD, including items relating to vision. Since our participants had their eyes closed, the comparability to other studies where these items relate to open-eye visual experiences is limited.
