Periodically I experience moments of dizziness where I can t even feel my own weight or a sense of gravity. At this moment I also lose partial hearing and can only hear sounds that are very close and even those seem to sound as if they are an echo under water. I have no sense of direction and can t feel which way is up or down. I have no feeling of movement even if in a traveling vehicle. I feel as though I am floating in space. Usually, these episodes last only a few seconds and disappear instantly with no after effects. I just recently experienced one of these episodes but this time, it lasted for several minutes. I m not sure how long exactly. In those several minutes, I also found out that I struggled to speak. I tried to answer a concerned friend but my words only came out as mumbling. After it passed I continued to feel slightly dizzy and I had the feeling that warm water was in the back of my head and was draining down my neck. This is the only time this has happened for this long a time. Thank you for taking the time to read this. Tom
