wh1578How much is the cost of the procedure, is there any specific data on the loss?
oscar459Does this still work now?
qslllIs there no way to retest?
EddieThe total number of dreams is 666.
diudiu.meiI'm not going to be able to afford to pay the bills.
Inventors quantify - small dreamsThe environment in which the re-test is performed cannot be 100% restored to the actual recording.
itaaaaWhy is retesting not important?
Inventors quantify - small dreamsThis tactic of retesting doesn't make much sense.
