Welcome to HCM.
Dreams are normal phenomena. Every individual will have dreams during a particular stage of disease. All dreams will not be able to be remembered. Only certain which were at the time of wakening or induced wakening will be come to our memory.
You had not mentioned your age. Nocturnal emission
of semen is also a normal event. If your don't have any type of sexual activity like intercourse or masturbation
, then you will have nocturnal emission. Semen will be produced continuously even though there is no sexual activity. If it is unused and the reserve is full it has to come out. It is not a cause for weight loss
. It is not a precious thing. Consider if you have already married and have regular sexual activity you will loose semen regularly. Anybody who has regular sexual activity will not have any weight loss. Likewise nocturnal emission is not a cause for weight loss.
For weight gaining you contact your physician. He/she will help you.
