ok..it appears as you re having a similar experience as i did with those videos ; first day pretty good but the subsequent days pretty average , the maker of the video suggests to view the video over 7 days which i have done , but as the results kept getting even worse i gave up after 7 days...I have been experimenting with a small strobe light hooked up to a programmable timer switch ; it allows you to have up to 20 programmes , so i got it programmed that the first one kicks in at 330am and switches off at 340am and i have another 5 more timings that swithc on every 90 minutes for the duration of 10mins , the light effect got into my dreams few times only because i am having trouble tracking my REM periods i am pretty sure if i could find a way to track my rem periods then i could work out the timer and the light would kick in at the exact moments when i am dreaming....i managed to get the lighjt ino my dreams few times and strangely enough they were dreams involving either a fire brigade , police or an ambulance LOL
so there is definitely a potential in there....The programmable digital timer switch is very effective and the strobe i have isnt very bright to wake anyone up its just right , all i need to do is to find a way or a device to find out my REMs....I tried the suneye method is also known as chakra induce lucid dream (CILD) I sometimes try it and get really close but not quite there yet...For some reason i dont respond much to the audio cues they either wake me up or no response maybe i gotta find the right recording with the right volume leves...
