TABLE 3.

Number of lucid dreams in different conditions.

	Study condition
	1 (60 min + MILD)	2 (60 min + MILD)	3 (30 min + MILD)	4a (60 min + Reading)	4a (60 min + Wii)
Nb (male/female)	11 (6/5)	15 (9/6)	14 (11/3)	11 (5/6)
LD (loose)c (male/female)	6 (2/4)	8 (4/4)	5 (5/0)	1 (1/0)	0
LD (strict)c (male/female)	3 (2/1)	4 (1/3)	2 (2/0)	0	0

^aControl condition. ^bNumber of participants included in the condition. ^cThree types of proofs were used to establish successful induction: (1) self-rating of lucidity, (2) assessment of the dream report by an external judge (3) LRLR eye signals on the sleep recording during REM. For the “strict” criterion, all (1)–(3) had to be met, while for the “loose” criterion only (1) and (2).
