Medical Weird Experience: Questions on Silver/Blue Micro-orgs & Sensation

[zorro]

I have two questions related to my experience. I don't know whether others experience it too.

1. Sometimes when I exert (force) with maximum capacity for an interval of time, I see Silver/Blue coloured moving micro-organisms in air. I feel slight dizziness at this time and this usually happens when I'm exhausted. What are they actually?

2. Whenever I keep a finger pointed between my eyes (very close to the skin) with eyes closed, I feel a different kind of sensation (some sort of pain). What is its origin?

I experience the former quite frequently. It's sort of a warning before black-out. My suspicion is that it's due to decreased blood flow to the retinae, which then produce random signals. Wait for an expert to answer, though.

The former can be a sign that your blood pressure is low, not enough oxygen is reaching your brain causing the distorted vision and feeling of dizziness. If you continue having this, it's worth getting a medical check-up. It is not necessarily caused by a vasovagal response (mentioned by the previous poster), although a result of a vasovagal response is a drop in blood pressure.

There is no distorted vision. I only see some strange glowing star like minute objects everywhere that too only for 10-15 seconds.

Exactly, those are not real objects so your vision is distorted. The stars you are seeing are called phosphenes, if they are caused by low blood pressure they are not harmful. However, there are more serious conditions that are associated with flashes of light, such as retinal detachment, so as I said: if you continue having problems it's worth talking to an opthamologist.
