Mental Imagery and Targeted Memory Reactivation in Insomnia

In this clinical trial, the investigators test whether mental Imagery Rescripting (IR), a technique where the individual is instructed to transform a negative memory or image into a positive one, and olfactory Targeted Memory Reactivation (TMR), a technique used to strengthen memories, can reduce hyperarousal and insomnia severity in patients with Insomnia Disorder (ID). Patients with ID will be randomized into four groups: in the first group (SH group), patients will have 4 weekly sessions (1 session/week) of a minimal intervention for insomnia (sleep hygiene information) in the presence of an odorless diffuser, which will be also used during the night. In the second group (IR group), patients will use IR during wakefulness to induce a state of relaxation and positive emotionality. More specifically, during 4 weekly sessions of IR, patients will imagine a negative scenario related to their pre-sleep images or current concerns (e.g., social interactions, self-image, sleep problem, nightmares) and transform it into a positive script. They will then perform IR every day for 4 weeks at home in the presence of an odorless diffuser, which will be also used during the night. In the third group, patients will undergo the same 4 weekly IR sessions and an odor will be paired to the positive imagery and will be diffused during the night (TMR group). Patients from this group will also perform IR every day for 4 weeks at home. Finally, the fourth group (OA group) will receive 4 weekly s…
